THE oldsmobile rocket 303 324 371 394 post to end all other posts, (lasalle related )

[RocketDaemon]

introduction:

Allright there is alot of olds posts here and there with information back and forth, making it hard to find information

so i figured i would try to make some sort of efford to gather all valid information and make some sort of faq post, that i will edit after things are sorted out and new things are added so everything is
sorted into catagories

I claim not to be an expert in anyway, i want to be though i crave more knowledge, and there for i wish to make it easier to overview and grasp all oldsmobile info there is...

all links to companies are in the links posts so its easier to keep them updated incase something changes..

I have set up an FOTKI account to host all pictures
PLEASE EMAIL ALL
PICTURES TO OLDSROCKET@FOTKI.COM
THE BIGGER THE PICTURE IS THE BETTER, PLEASE DO NOT RESIZE
PLEASE DO NOT POST PICTURES IN THIS THREAD IF POSSIBLE

here is the photoalbum i will post everything i have gathered
http://public.fotki.com/oldsrocket/

Thanx to everyone who helps expand this post:

Paul, heathen, Royalcrown32 etc



PLEASE if i enter something that is wrong/false please correct me...

Fuel injection
Hilborn:
made several for olds, atleast 3, 303, 371 and 394 to my knowledge
these could ether be dist driven or camshaftdriven by using an timing cover..
or driven by fan belt , belive there was an beltdrive part to put on the same
pump that would go on an timing cover.


Supercharger - blower intakes , crank pulley and all parts surrounding

cragar:
cragar made as far as i know 4:71 intakes + 6:71 intakes

i belive 471 cragar intake came with and without water passage in front
(as seen in pic below)

i've seen on ebay quite often that cadilliac 471 intakes are misstaken
as oldsintakes, so beware, but on the otherhand cadillac cragar intakes
bring a little more money so in worst case you just can flip it and earn something from it incase you bought the wrong item...


Weiand:

1949-1956 - 303-324 - for 6:71
1957-1958 - 371 - for 6:71
1959-1964 - 371*-394 - for 6:71


Supercharger - blower brackets
Mcculloch supercharger bracket
Mcculloch made an bracket to put the vs-57 supercharger (the one studebakers and kaisers used), on an stock or aftermarket intake, it will basicly mount
on all intakes that has the generator holes on the driverside, but might not clear
for instance 3x2 edelbrock intake, i have an such bracket and and a couple of ol-396 edelbrock intakes, but i do not have an supercharger but seems supercharger would interfeer with first carb, but will of course work on stock intakes,
with either airbox or xxxxxx.....
i got some old mcculloch parts manual that i will scan and add here asap.
more info to follow
also needed is a crank pulley...

Note on transmissions, i will ONLY include all lasalle transmission, the "buick" style selector 1951+ manual, hydramatics + 1953 dynaflow,
there is adapters to use "1939" ford trannys aswell as t-10, t-5 style etc i see no need to have any indepth information regarding those transmissions except on how to mate them to the rocket...


Manual transmissions

1949: No manual transmission

1950: the only year of the side shift lasalle tranny with short tailshaft + only bellhousing from olds that works with other lasalle trannys

1951+ not same as 1950 olds, lasalle do not bolt up, same flywheel and clutch though,1951+ is a selecter type, not as bullet proof as lasalle 1951+ can use early buick tranny though, early buick trannys are almost ast bulletproof as lasalle, some parts even interchange inside them

note that cadillac 1949?, 1950,1951,1952,1953,1954 has the same bellhousing as oldsmobile, and that many ambulances aswell as funeral cars could have lasalle trannys, though is 1950 olds the ONLY year with shorty tailshaft, the 1949-1954 has the same bellhousing as 1950 olds though ( i am not 100% sure if 1954 cadillac had the manual trans, did they share infact the same flywheel as earlier olds in 1954 for manual or did they use 176 gear flywheel in 1954?, i own an 1953 cadillac tranny .. pics below)

Early Olds Rocket tech summary

One note on the Cadillac bell housing--it will fit the Olds block and uses the LaSalle type transmission, but does not have provisions for mounts like the Olds bell has.

[RocketDaemon]

paul:
kinda hard to find the info when so many people post, i just wanted to clean everything up and gather even moer information and pictures then anyone did before..

heathen:
are you sure? my black 1953 bellhousing and 1950 olds bellhousing seems to be the same? havent compared exactly but just looking on the pics they seem the same, what mounts are you refering to? the ones on the side? that the black one has? maybe my black isnt 1953 caddy but 1950 olds? not impossible as i was just told it was 1953 caddy, could be 1950 olds bellhousing with earlier lasalle tranny

When I dig out the Fenton headers for a photo shoot, I'll take you one of my Cadillac bell housing as well. Other than no mount provision, it also has cast in strengthening ribs.

[Stone]

Thanks for the info. With some much stuff out there being posted I found it hard to search and get the answers I was looking for.
Again thanks. I found this on the web. Kinda gives the storie on what went into dsesigning the rocket.

[racer756]

Thank you for consolidating this info. It IS very helpful.

[Durod]

man i've got all tha badass rocket threads saved somewhere on here. lemme see what i can dig up... thanks Daemon, you rule.

[Billy the kid]

I aquired my first rocket yesterday, a 53 303. This thread has taught me a lot already. I will be going to the back yard very soon to see what I can find on the survivor. Thanks for the effort and the info.

[RocketDaemon]

thanx for all the info everyone is adding, i will try to post stuff into this thread everyday if possible.

i added some stuff lastnight and this morning, there is still alot to add, i've got some stuff still in my head to write down, aswell as hunt down all the other posts and gather information from them..

[Dago 88]

Thanks Daemon, love it. Do you need more pics ? I have a Hildebrandt starter cross over if you like & some other goodies. If you like i can take some pics on the week end.
Cheers Dago.

[kustomolds]

Great thread! You are right, there is a lot of info on this board and it will be great having most all of it right here in one thread.....

[seymour]

If my internet is working later this week, I'll dig out some of my Olds junk.

[CGkidd]

I wiash I was at home to take pics of some of my items. I have a Weiand tripower for the 324 and Cragar 4 deuce.

[**MCQUEEN**]

I'll play

[RetroJoe]

It would be nice if this could be made into a sticky! I have a 56' Olds that I am building and am always looking for info on them.
Does anyone know if you can adapt a newer trans to the 324?

Correction: Although referred to as a Frankenstein Magneto a few times in this post, this mag doesn't have a specific name, but is most commonly called a Harmon/Collins style, Schieffer, or Cirello-Schieffer Magneto. Cirello did make and market a Frankenstein Magneto ( with bitchen graphics ) I will enclose a link to a Cirello page.
Damon, cool idea with consolidating everything. I will try to get you some pics of some junk I have collecting dust. D.

Yes you can. It will cost a little bit of dough though. Just ask Coaltown-- LOL

I'm afraid to ask now! I guess it would be cheaper to install a Chevy motor/trans in it, but I would be killed by the Olds guys!

Hey Daemon... what happened to the photos???

[RocketDaemon]

Hey everyone, photos is "gone" just because i apperantly have to pay for the fotki.com service, so either i will pay or find another photosite, don't mind the paying part if somethign works fine, might change to photobucket if thats better

also check the Tech there is a DIY adaptor for later auto in there.

[vintakes]

olds cam and lifters
49-55 cams interchange app 1 3/4" cam bearing dia lifters same dia as chevy
56-58 cams app 2" cam bearing dia use large 921 lifters
59-64 cams longer than 58 also uses 921 dia lifters
late model olds diesels use 921 lifters simply collaspse to make into a solid lifter
not sure when olds went to the larger cam journal sizes or if any motors carried over in yrs john

[nummnut]

keep it comeing grat post.thanks

[Wasahawaiianrat]

I'd really be interested in the mcculloch supercharger info/ brackets for the olds. I was thinking about puting one on mine because they put out a low amount of boost and my motor has high comp with the jahns pop tops.

[DeucePhaeton]

this is outta the years dicussed here but the 66 442 had a dealer installed optional 3x2 set up avalible.

[Blownolds]

The only Olds years ever available from the factory with 3x2 was '57-8 and '66. J2 was '57-8 371 only.

[DeucePhaeton]

My comment was in addition to the J-2 from 57 and 58.

Another addition: Not all J-2 manifolds came as J-2s.
Explaination: My father bought a 58 Olds in 1958. Car came as a 2bbl and had a J-2 intake with plates over the end carb mounting positions.
he told me this years ago in conversation about car stuff. He was a General Foreman in the Engine Plant at Olds in Lansing. Said quality was different then. It was a way to lose the inventory not sold. (ordered as J-2s)

What happened to the pics?

we should work on this so i can stop getting phone calls and PMs alll the damn time.

BTW anybody who is curious,NO, i will not rebuild your hydro,NO, i do not have a "spare" flywheel,and NO, i do not have any adjustable rocker arms.

i WILL photocopy articles and service manuals,and i WILL help you adjust your hydro if you live nearby,and if you are willing to pay for the pizza.

This thread RULES! Its like a beacon to a fella in my situation!
Does anyone know what engines will bolt up to a 55' olds hydramatic? Second question: Does anyone have an engine that'll bolt up to this transmission they are interested in selling?

[RocketDaemon]

BEHOLD pictures are back up!, coughed up 30 bux for an 1 year subscription to fotki
added some pictures in the album , added a picture of my supercharger setup also

[mpls|cafe|racer]

When are you gonna add a picture of you boxing the supercharger setup up to send it to me?

any 1949-1964 olds engine
or cadillac 1949-1954

or getting an correct bellhousing you could put it on an csb

but i would of course recommend the oldsmobile route

[backyardbeliever]

DAEMON i just caught this thread for the first time. WoW great thread , im finishing up my build on my blown 394 for my 37 chevy gasser. and in the process of that build i have learned the HARD way how to identify weiand WO671 intakes. In the picture you posted of yor 394 blower setup. take a close look at the intake mounting holes and you will notice they are drilled in a slightly different position in the cast in space provided in the raw casting (easy to notice on the center ones)as Weiand used the same casting for all years 49-64. (besides the diff. in pop off location) they just drilled the mounting
holes for the different years in just slightly different spots. The pic you posted (labled 394 blower setup) is of a 49-56 WO671 intake . Here is one of a 59-64 394" WO671 notice the hole location in the center. Dont be fooled by port size on these intakes most have been cut. as i stated i have learned the hard way as i own 4 of these.
weiand did stamp a number or a letter between Weiand and WO671

"56" or "A" = 54-56
"57" or "58" or "B"= 57-58
"59" or "C" = 59-64

i hope this helps the post , ill take some pics of my goodies and post em. Thanks

[RocketDaemon]

Hey!

ohh so i don't have an 394 blower intake afterall?
well goodthing is that i got several olds engines, 303,324,371,and 2 394's so i can use it on another engine instead
but darn in that case my plans for my 1934 coupe is alittle bit halted at the moment though .

[backyardbeliever]

well the one i have pictured is a extra 394 one i have . anything to trade? what is your manifold stamped number or letter?

[TrailerTrash]

Man, here i thought you had to swear a blood oath not to divulge this info in order to have access to these "secrets"...LOL!
Thanks RocketDaemon for taking the time to share this with us!!

[kiwi88]

Thanks for the info Daemon. Can you tell me, will an edelbrock ol-396 3x2 intake fit to an Olds 303? Thanks

[RocketDaemon]

no problem, but its not all my work i've learned alot and "stole" alot from other threads here on hamb aswell

yes it will, it never hurts to port match the heads though
or intake etc..the ol-396+ol-496 intakes all fit all 303-324 engines but intake ports on either head or intake might not be 100% the same, so if you want to earn som hp matching never hurts..

[kiwi88]

Thanks.

Another little challenge I have is we are missing a roker arm for my 303. Replacements I got from Egge are slightly longer and lead me to believe they are from a later model motor. Talking with Gary at Rocker Arm Specialists to see what they can do. Do you have any other suggestions? This is all we're waiting on to get my rod going and I'm not as patient as I used to be.

[Paul]

the longer ratio arms need the coresponding towers
to center the push rods in their guide holes

but are worth a few more horse power if ya do

[Paul]

thinking about this one again,
does your short ratio rocker take the smaller 1/4" diameter push rods?
the longer ratio rocker should take the larger 5/16" diameter rods
so that means to do the swap you might need lifters, rods and towers
and new lifters should go on a new cam...

stock cam could be reground if it's a good one, might be a good time to add some "bump" it
early (all?) 303s will take a common Chevy lifter
and check push rod length, they should be "off the shelf" stuff too

[HEATHEN]

You should use the larger pushrods with the 1.8 rockers, but the early lifters can stay.

[backyardbeliever]

does anybody happen to know if a 455 bronze dist. gear can be made to work on my 394 roller cam? It looks like it would work . has anybody done this?

[superjunkman]

Thanks Daemon, great thread. I read all the text and clicked all the links and am still a little confused. I'm going to be putting a 324 with a j-2 intake machined to fit in my roadster. I really want a manual transmission. I don't see any reference to any olds standards for the 324. Was the Hydramatic all you could get? If I want to use a more modern GM manual is spending $1,400 on the adapter kit my only or best option?

[HEATHEN]

The standard transmission that Oldsmobile used from '51 into the early '60s was a "selector" three speed that had a unique bolt pattern and the only companies I know of that ever made a floor shift conversion for it are Ansen and Drag Fast, both of which are long out of production. My '64 Hot Rod magazines have ads for four speed equipped Starfires, but I've never seen one.

[arkracing]

Lots of great info here.

I have a dumb question

I know you have the years for cid listed, but what types of cars should we be looking in? I know "Starliner" is mentioned alot. Do all Olds cars in those years have "Rocket's" in them.

I'd love to find a '61-'64 394 or a earlier 371, but not really sure what type of car I'm looking in - anybody have pictures of what these came in or have a source for pictures? Even pictures of the earlier cars as well so some of us rookies know what to look for.

Thanks

[HEATHEN]

All '57-'58 Oldsmobiles were 371 equipped. The cheaper '59-'60 models had 371s, and the more upscale models had 394s. All '61-'64s had 394s, except cheap '64s, which came with the new 330. '59-'60 371s were a high deck block like the 394s.

[DeucePhaeton]

When Olds went to the overhead valve engine in 49 they started the "Rocket" theme. That was used by Oldsmobile pretty much from then until the engine went away about 1988. The "Rocket" engines were the V-8s produced in Lansing. All Oldsmobile V-8 engines were produced in Lansing but now all Olsmobile V-8 cars had engines from Olds. ie 1977s.....
For your search just look for any Olds up through 1958 for the 303, 324 and 371 config. The 59-64 full size cars for the 371 later design and 394 except the less expensive full size models. The early 371s mount the valve covers thru the center of the cover. The later mount at the perimeter.
Hope this helps you a little.

[skunk victim]

is there any problem bolting a complete 49-53 cadillac bellhousing to a olds rocket? i dont think there is but maybe i am missing something

[malkintent]

guys this is a great thread thanks for all the info.

again

[55olds88]

by the looks this hasn't been covered, will 57 heads fit earlier engines ? I know 56's are better then 55's they are also harder to get, do 57's fit and if so what needs to be done ??

[bushwacker 57]

i have a cad bellhouseing appears the clutch fork is mounted lower than olds . compare and see.

[HEATHEN]

Yes, '57-'58 heads can be used on earlier blocks, but since the corresponding intake is too wide for the '49-'56 block, you'll have to port match an early intake to the larger head ports as best you can. Also, the '57-'58 rocker shafts are slightly longer, and will need either the late valve covers, or reliefs beat or ground (tin or aluminum) into the early covers.

[HEATHEN]

Also, the Cadillac bell housing has no provisions for mounts.

[bushwacker 57]

HEATHEN rocker shaft dia is cad - olds is it the same. 49 up thanks.

[HEATHEN]

Cadillac rocker shaft diameter is not the same as Oldsmobile.

[55olds88]

FYI there is a mob selling new Olds Rocker shafts on ebay at the moment, pretty reasnoble pricing too.
Thx for the 371 head info.

[unclescooby]

Great thread. I'm wondering about actual physical size though. I'm assuming that a 394 is physically not larger than a 303 right? Just a bore and stroke difference? How much larger than a small block chevy in size is a 394?

[HEATHEN]

Yes, a 394 is a bit larger than a 303, due to the deck height being taller, which makes for a wider block.

[unclescooby]

Thanks. Any idea on weight?

[gwhite]

Speaking of width, can anyone measure the width of both a low-deck and tall-deck for comparison's sake. Overall width and width from exhaust manifold to exhaust manifold would be nice.

Thanks!

[langy]

My 394 isn't much longer than the SBC it replaced although its a whole lot wider.

[jakespeed63]

Got a complete '64 Starfire engine with all the accessories, under the workbench.
Width @exhaust manifolds:24"
Heightil pan to carb top:26"
Length;water pump to bellhousing:31"

Weight: Them Sum-Bitches are heavy as a boat anchor, almost crushed Nads chest puttin' mine in the Olds.
Betcha it weighs every bit of 500lbs, probably 750 with all the accessories.

Can anyone tell me what 5 speed trans i can adapt to the offenhauser #0304 adapter? i can weld up the mounting holes and re-tap. just not sure what trans would have the correct shaft length. i plan to put it in my 32 ford

[GOATROPER02]

I have new aluminum bellhousings for early rockets for use with a muncie or 5 speed

[1949Olds98holland]

This is great information SUPER.....

Now a real stupid question
I have an 1949 olds 98 2dr Club Sedan. Sadly no body parts appear to match any other oldsmobiles or Chevy's. The problem is the longer wheelbase 122 inch instead of 119,5. My question where is this extra 2,5 inch added. Is it in the body or fenders? Where exactly is my car longer than a 88 2dr club sedan.

Hope someone can help

[Dago 88]

I think you will find it is longer in the front sheet metal .The 98 body is the same as Buick & Cadillac, & the 88 body is the same as Pontiac & Chev from the cowel back. I have also noted that 98's have removable rear guards & the 88's don't. Can any Rocketeer's confirm this? Got any pics of your car ?
Hope I was off some help. Cheers Dago.

[1949Olds98holland]

[1949Olds98holland]

Thats the car... The reason I am asking is I need to replace almost everything.

After looking at a lot of pictures I think I can use the rear lower qtrs from a 1949 chevy for restoring my qtrs (my qtrs are already molded to the body) The general shape is the same. Am I correct?

I will be using 53 front fenders for restoring my 49 fenders I will let you know how this can be done when I receive them

Since I live in Holland there are not to many parts available so I have to work with what I can obtain through ebay and such

Outstanding thread! I have two items to add:

1) I worked w/ Copper Gaskets Unlimited in AZ and they made me copper exhaust gaskets for a 1957 371 and they are now in thier database.

2) Currently working w/ Harland Sharp for custom roller rockers (works on stock shafts) for the 371. I received one initial protype a few months back and I am currently awaiting the next round. I will keep you all posted...

Guys, .. even though it was posted a while back and i haven't been here for almost one year,... this is an post about OLDSMOBILE ENGINES
not sheetmetal and brakes etc.. ONLY engine/transmission related.... (could maybe expand to olds rear ends though but ahwell..)

the fotki pic page is down due to that i havent paid anual fee
i will sort that out in the next few days and post new pics there etc..

[F&J]

i will sort that out in the next few days and post new pics there etc..

Thanks in advance for new pics, glad you are back

Glad to see this old thread alive again.

57olds -- thanks for posting the vintage pics.

fanspete -- that set up looks badass!

[flatoz]

I read an article that I found by accident in an early american rodder on early Olds rockets and this was prior to their being rebuild kits around. they said that FE 352 pistons fit and have the same pin height etc, just bore the motor out and from memory you get a 346.

[Paul]

those pictures are priceless

[CGkidd]

Flatoz you are correct. You also have to replace the bushing on the small end and hone it for the 352 pin which is smaller than the olds pin. Stock bushings will work. I concure with Paul those pictures are priceless.

[panhead_pete]

Hi guys, do the 371's mount from the front or is there an optional side mount? If possible I'd love to see some pics of motor and the stock auto mounts in A model frames. Thanks guys, now that I know I can use the stock auto Im getting pretty sure Im heading down the olds road if this 371 checks out.

[ANDY M]

I know where there is a 1960 Olds complete drive train.



It was mentioned in this thread that I have been posting to.

http://www.jalopyjournal.com/forum/s...d.php?t=341294

I asked what it might be worth. It came out of a wreck that had less than 3000 miles on it, and is factory original right down to the plug wires and radiator hose. The bad news is that it's been sitting in this garage for 50 years, so it may be a little rusty on the insides.
Anybody that's interested, please send me a pm.
Thanks,
Andy

[RocketDaemon]

some of the stuff i recently bought

mt pistons, another setup of 394 pistons, 2 camshafts,
just bought an 1957 oldsmobile with 3 371 engines...

going to buy 2 more engines soon, one here in sweden and one more in the states

howdy!

and oh forgot to mention edelbrock with valve covers with 57 under edelbrock logo, weiand 324 intake with 6 carbs and water cross over, and oh yes an olds 394 dual 4 intake and 2 500cfm edelbrock carbs, going into my 1964 olds dynamic

eventhough this thread is about engines, these 2 cars do got engines in them that are olds, the 2x4 will as stated go into my running 1964 olds, and the 6 carb intake with edelbrock valve covers will go into this 1957 oldsmobile

probally forgot an whole bunch of stuff i bought for the past months, i haven't been online on hamb for almost a year so..

[RocketDaemon]

pics to post above

and oh btw, i am just upgrading my fotki account again
to pro, so pics will show again and i will add more pics in the album and clean upp as much as i can in the next few days...

[RocketDaemon]

also, i really would like to see s.co.t blower intake for early olds
and i would heck also really want to buy an scot blower intake for the olds
i really would love to put one scot blown oldsmobile engine into my 1941 buick convert. either that or i'll just stettle for an edmunds intake and valve covers..

[gonzo]

56 Olds with a Weiand 3 carb set up with Rochester 2gcs and a T5 hooked through a Bendtsen's adapter. Motor mounts use early ford mounts and are made by a local speed shop.

[57J2]

Cool thread. I have a couple of questions I hope someone can help me with. I have both a 57/58 371 with auto, and a 64 394 with auto out of a Starfire. Are either or both of these a bolt in to a 49 88 or anything major have to be done to do it ? What engine would be better considering rebuild costs(budget minded) for the best performance, considering a street with occasional strip application, also keeping in mind as funds become available adding more aftermarket speed components later ?

[bubba67]

Whats the better hot rod trans ? The Olds Hydro or the Jetaway ?

[BLAINE 816]

Thanks for the info. Looks like a lot of work.Blaine

[RocketDaemon]

Bubba67: do not use the word hotrod trans in the same sentance, as Jetaway, hope that answers your question...

57j2: i would go with the 57 + tranny... , or get an early waterpump housing on the 394, but i would personally prefer to use the tranny from th 57 so all in all i belive putting the 57 engine in would be easier... 57 is an much better tranny imho!

There is also the 3285 for 54-56. Its a 2x4. But I want to know if a 3200 for a 49-53 would fit on a 55? I notice some manifolds such as edelbrock's say they are for 49-56 so I dont know why offenhauser would have two different ones.

the intake ports on '54-'56 heads are taller than the ones on '49-'53 heads.
some intakes,like the Edelbrock OL396 3X2,are cast with the shorter ports,but enough meat on the manifold to open'em up for the later taller ports.

So the offenhause cannot be made to fit on #8 heads?

[Paul]

here are three examples of some of the magnetos that were available

a Ronco in a Cragar 4x2 inducted 324 (mock-up stage)


a Vertex in a Offy 2x4 inducted 394 (also mock-up stage, but a little further along)


and a tach drive Joe Hunt in a 4-71 blown 303 driver

[PROSTOCKTOM]

I have a question about a 371 3x2 intake.

Who made the coolest looking one, and which one performed the best ?

Thanks Tom

[Paul]

beauty is in the eye of the beholder, and "worked the best" at what?

in my opinion, you can't beat the looks of the stock tri-power on a 371.

the only 3x2 Olds I've owned was on an Offy intake on a 394
and it was just about perfect for the 2,000 lb street car it was in

[PROSTOCKTOM]

Ok, I changed it to performed the best

Tom

measuring some of the heads laying around here,
and these are aproximate numbers,
castings vary slightly and gaskets will be a touch bigger typicaly as may aftermarket intakes

303, 1-1/8 x 1-5/8
324, 1-1/8 x 2
early 371, 1-1/4 x 2
late 371 and 394, 1-3/8 x 2-1/2

I've got a set of Gotha adjustable rockers. I've read online that since there is no locknut on these, they have a tendency to loosen. My question is on the side of the adjusting bolt there is a hole, could this be tapped out to accomodate a set screw?

[HEATHEN]

If there is no lock nut, then the screws should have interference threads. Many Ford adjustable rocker arms came with interference adjusting screws from the factory, and didn't have a loosening problem. In fact, I used some 223 Ford screws in the rockers on my Chevy 235 and they've worked fine.

[NotNuRodz]

Hey guys i bought a 62 four door Olds 88 this winter and i am just now getting a chance to work on it. The car has the 394 in it and I want to put dual exhaust on the car, but the exhaust shop is telling me that with the drivers side exhaust manifold thats on the car its not possible. So my question is to you guys is there an exhaust manifold i could put on the car that will go around the steering and allow me to put on twice pipes (i was thinking maybe something off of a two door, or aftermarket even). I'm sorry if this doesn't fit into this thread but i figured if anyone knew about olds motors they would be on this thread. Thanks in advance.

[Paul]

yes, the factory did make one that dumped at the rear.
not common but they are out there.

I sold one not too long ago,

here is a home made version someone made by removing the stock dump, welding some plate over the hole and welding a new dump on at the rear

[Paul]

and here's a couple pictures of my old stock one

[NotNuRodz]

Thanks paul i heard rumors that it would be hard to come by (and a little costly). I think im gonna get a second manifold and try that home made one.

[ROCKET88COUPE]

tks for the info,when u need it its hard to find,on the later 394s what year did they change the exhaust manifold?im running a 60 394 block and 23 heads and have noticed earlier heads have diff ex manifolds

[NotNuRodz]

Well i've been hunting all day (ebay, craigs list, HAMB classifieds!!) and i have had no luck even finding a non dual exhaust manifold. If anyone has a drivers side exhaust manifold (dual exhaust or not) for sale please email me at evanbeiser@yahoo.com or send me a pm please.

[bubba67]

Does anyone know a source to buy a Hydro tranny to put behind my '56 324 ? Fatsco in NJ ?

[joewit]

Does anyone have pics of a 2x4 setup on a car with a hydro trans. I want to see how the trans linkage is hooked in and not innerfering with anything else.

[joewit]

Figured I'd showoff my parts too.
Offy 2x4 with I think '53 rochester 4gc's and
Gotha adjustable rockers
I also have a isky cam and mallory dual point dist. Does anyone know of a simple way to find the specs of a isky cam?

[TONY CARTER]

Hi Guys,just joined.I am building a 32 Ford Roadster,with a 1957 Olds 371 Motor.On the back of the block there are casting numbers that read.
342 CFD,cast No 568929,engine No A083170.What does this all mean.

I pulled the motor apart and the mains are 30 thou up and are still a little scored.I see that Kanter make engine rebuild kits that are 30 ,40 and 60 thou up.Can I still grind the crank down.Or can anyone point me in the right direction to get another machinable crank ,or even a NEW crank.What do you think.

[racerjohnson]

Tony, I think you should go to the intro section and introduce yourself.

[TONY CARTER]

Couldn't find the intro section.Where is it.

Is a 394 Crank the same as a 371.I'm trying to find new engine rebuild parts for my 371,Rocket engine.To be shipped out to Australia from Stanton,LA ,in the 3 weeks time.Any help with the right parts and suppliers here would be great.
Thanks Tony.

Thanks Tony.

I need to know what year engine is,and I can supply anything you possibly need

Also what part of Australia as I have freinds there also and combine shipping when possible

Hi Tony,
on the back of the block it has on top of the bell housing.Cast into the block,,342 in a circle a star,CFD, Engine No Ao83170,it was in a 1957 Olds Rocket 88 4 Door Holiday Sedan.
Wow that is a mouth full.
I am needing a good sized Crank,mine is 30 thou up and still has scores in it.Full engine rebuild kit,pistons rings,bearings,cam,New internal Oil pump,Full gasket kit etc.
My engine is in the Hot Tank as we speak so I will get the measurments of the bores to you ASAP.

Is Ohio near Stanton,LA,California,that is where the container is leaving in 3 weeks.Could you email me individual price listing of parts required.
I would need all these parts delivered to Stanton using internal freight in the next few weeks ready to be shipped off to Australia.
Is a 371 Crank the same as a 394?
Tony Carter.

[TONY CARTER]

I found a 394 Crank for sale.In the USA.Is it the same as a 371 Crank?I'm told it will fit in the same.
Then what is the difference of a 371 to a 394?

[GOATROPER02]

The Main Journals are a different size,and front length can be different

Tony

[GOATROPER02]

TC did you get my Pm about having a crank for your engine?

Tony

[TONY CARTER]

Hi Tony Lombardi,
No all you said was you were back in the shop.

I live in Maryborough ,Queensland,about 3 hours north of Brisbane,near Bunderburg.Yes where they make Bunderburg Rum.Just near the Great Barrier Reef.

The bores are already oversized and scored so I have been advised to sleeve the block back to standard.At least it is all brand new then.

The only unknown is this 371 Crank,I can buy all the other bits no worries from Egge,Kanter,Fusick,etc.
What size is the 371 Crank,can you supply it machined with bearings ready to bolt in.And at what price in AUD.

Also can you get different cams for the 371.

The heads are mint,they have been crack tested are are in great shape.They just need new Exhaust valves and seats.The J2 Manifold is also in Mint Condition,Olds Cast Iron one.Just missing all the carbies and progressive linkage.

I'm looking at some Rochester 2G carbies on Ebay at the moment.I want something that is all rebuilt,bead blasted ,with a rebuild kit,NEW GASKETS READY TO BOLT ON AND DRIVE OFF.

Tony Carter.

Has anyone used a J2 trypower intake on a 324? Can you milli down the heat crossover and weld a plate to cover the hole to clear the valley pan

you would also need to try to get the ports to match up

but not sure why you'd want to go through all that
they are heavy,
and aluminum versions that actually fit are readily available

I have heard somewhere before (possibly here) that early Hemi intakes could be adapted to early Rockets (not sure which ones); has anyone ever heard this before?

[TrailorPark]

Hey Bro, this is one of the best post I have ever come across. I have a 58 Olds and have been scratching my head on where to look for anything related to the engine or trans. Thank you for your effort and time to put all this together.

[Paul]

'starting to piece together another blower motor,
here's an early mockup picture of it sitting on a late 394 in the A Coupe
but the plan is to put it on a 371 in the A Roadster
that is if I can ever get out there and actually make some progress

[badsco]

I recently purchased a '61 394 Olds motor to put in my '47 Olds. Deadly opposed to a SBC swap, I stumbled onto it in the local classifieds. Been researching them since, and figured I was at the point to ask some questions
The motor is a 2bbl so assume it is the lower compression version. With the deal I got a set of starfire heads. Just wondering if it would be worth it to swap heads or not and if I'd see any improvement or what the difference is between them. I would upgrade to a 4BBL intake at the same time and probably a cam if I go that route.
Also, for all the links and web sites I've followed and found, I cant say that anyone actually stocks cams for the 394 - am I missing something here?
Thanks in advance

[3x2rocket]

you can still get all the internal engine parts, Egge, Kanter's, and falcon just to start with.

If you want a performance cam pm Goatroper02, you'll see posts from from him above in this thread.

[D.SCOTT]

so anyone know the difference between starter crossovers? they are not all the same, and some are not labeled or numbered as to what they will fit. i would love to see a list of makes and applications. i challenge you!

[badsco]

Thanks, I checked them out and did PM Goatroper02, going to give him a call

Anyone know the difference if any with the Starfire heads?

[Paul]

don't quote me but I think the heads are the same

it's the pistons, cam and 4bbl carb that bump up the hp.

the '62 up heads have a slightly different combustion chamber shape,
designed to burn lower octane and still keep the compression up

[Paul]

yeah, gotta drill and tap the block for front mounts
the wood blocks get in the way of the fuel pump and exhaust..

[3x2rocket]

badsco, the starfire heads (#23) should have larger ports and better flow, I believe they also have a different exhaust bolt-pattern. I'd recommend using them.

[skwurl]

Dang. you go too much time on your hands

[oldsboy]

Does anyone have advice in putting a 371 in model a rails? I'm getting to the point of mock up and wanted to see if there was anything to look out for. (Pics would be great)

[Paul]

my #23 heads take the same intake and exhaust gaskets as my #20 heads
ports measure the same, bolt patterns are the same
can't say about runner shape or volume though

[3x2rocket]

Huh, I always thought the term "starfire heads" meant they were special, I doubt there are any design differences inside if the ports are the same. I think Paul has debunked this myth... Still at least it sounds cool to say "its a 394 with starfire heads"

Thanks guys, picking it all up in the next week or so, will have a good look to see if / what the differences are and report back to this thread - be interesting to know anyway.

That will teach me to refresh the thread before replying - seems indeed the myth is busted! Definitely cool to say it has starfire heads though.

[HEATHEN]

All Olds heads had the same exhaust manifold pattern from '61-'64 (talking big engines only).

[HEATHEN]

My '64 394 has a smaller diameter flywheel than the '49-'58 engines did, and takes a different starter. I've seen aftermarket lower housings with bosses for two different starter bolt patterns; I assume that one is '49-'58 and the other is '59-'64. Although '49-'53 flywheels have a different number of ring gear teeth than '54-'58, I think that the difference is made up on the starter gear.

[TONY CARTER]

(1) I found this crank on Ebay,will this Crank fit in my 1957 Olds 371 Engine.
(2) Can it be Machined to fit,
(3) Is the 371 Crankshaft the same Casting as a 394,but with different machining.

http://cgi.ebay.com/ebaymotors/ws/eB...K%3AMEWAX%3AIT

On the back of my block it has 342,CFD,casting No 568929
Engine No is A083170.
On the front of my crank it has two holes in it one on each side of the journal.
It came out of a 57 Olds 4 Door Holiday Sedan.

Need an answer ASAP please Clarify.PM me if your sure.
Tony.

[power58]

Great work, Great photos, Thanks for posting

Hey Olds Boy,
I put a 371 in my 32 Ford roadster and I made up a engine cradle that bolts up under the original front mount (4 Bolts)but then is spread over to the out edges of the rail where the Front crossmeber is welded in.In the corners I mounted Old Sidevalve Donut mount in the Corners.

My engine crossmember is made out of 75mmX 50mm X 3 mm mild steel and is shaped like a Boomerang.With the donut mounts in the corner of the Chassis it gives it a pretty stable front mount.

Tony.

[TONY CARTER]

I found a Crankshaft from Mike at RPM Motorsports, on EBAY,he has been great in comunications and accurate information.

Very happy to be able to get on with the build of my engine now thanks Mike.

He is Junking a 57 Olds now if anybody needs some bits.

Thanks for the heads up! I need a few odds and ends.

[TONY CARTER]

Old Soul,
My engine is away gettin built,I'll try and take some photos of the engine Mount sitting in the Chassis.Would probably be a better photo anyway.Without all the clutter of Radiator Grille shell,etc.

Cool, thanks!

[iafraser39]

I had a 394 olds bolted up to a 55 B&M hydro.
I think the engine year was 1959, though not sure.
Never had a bit of trouble.

[bones35]

So I've got a new idea for splitting the center exhaust ports on the 324 heads. I'm getting ready to build some headers for my olds using the flanges available on the web. I just sent my heads out to be decked and don't want to do the heating and welding now but I want to get them split. Here's what I've come up with. I'm going to be welding a tab onto my flange that protrudes into the head out of 1/4 inch. It looks like I will need to take away some material on the top of the port since it comes in a 1/8 plus to allow the tab to slide in and be tight the whole way back. I will square of two sections of 1 3/4 tubing to fit flanges and then split them to fit in center flange. After they fit i'll weld a peice of sheet metal to one side of the split tubing and to the new tab to give support and then weld the other tubing on to complete the connection to the flange. What do you think? With the solid mount i should be able to fit the tab tight using a gasket on mockup. I'll keep you informed I just ordered the flanges.

[TONY CARTER]

I'm just starting to make my own Headers too Bones.I have just bought some normal 1 3/4" Exhaust tube.
I placed 2 X 1 3/4 tubes on the Simese Port and where they overlaped I marked them and cut out the inside third of the pipe and then taked them back together

I wanted to have 1/3 lap in the pipes on the centre Simese Port. So I still have two pipes comin out of the centre port.I have seen the Olds Motors like the Sidevalves with only 3 Exhaust pipes,but I dont like the way it looks like.It looks like a V6.

I'm trying to do something a little different as always.All my pipes will be Tig Tacked and then Braize Welded and then Polished out.
We do this all the time on Handrails that we make at work for the Australian Trains.
It looks really cool.
Lot of work but so was the rest of the car,no rushing it now.
Tony.

[Paul]

blurry pix of the various exhaust port configurations through the early Olds' run

the 303 with oval center and round outer ports



the 324 similar but with rectangle center and square outers



the early 371 similar to the 324 but slightly larger ports



the late 371 still two bolt center port but now with runners devided all the way to flange surface, larger ports



and finaly the 394 three bolt and devided center ports, all ports larger again

[TONY CARTER]

So Now I know I have an early 57 OLDS 371.I have the same ports in mine.
What sort of Cam would I be looking for for a Daily Driver.With a J2 Manifold on it for the Nostalgic Look.I'm not a Drag Racer or anything just want it to run with a nice note and idle without lunging forward.Like huge cams do.
Does anybody know what Cam No to look out for?
And where do I get a Cam and how much do they cost.
Thanks Tony.

[Large_911]

I got mine from Camcraft Cams. It appears that they changed the website a bit, so you would need to call them. I am building a 371 too -- shoot me a PM.

[ALLSTEELWILLYS]

Does anybody know were i can find a set of forged pistons for a 1957 371 olds?

Also a good nice "lumpy" cam?

Thanks

[GOATROPER02]

I have everything you need for your early Olds... stock or speed

Thanks,Tony

[TONY CARTER]

Yeah I got a cam from Charles at CamCraft and it only took 10 Days to get it from the States to Australia.Very happy.

[Mike B]

What are the differences in the 56 324 and the 57-58 371 block besides the bore? If just the bore is different, how much can the 56 324 be bored too? I guess what I am asking is can an oversized piston made for a 371 fit in the 56 block?

Mike

[HEATHEN]

Lots of guys used to bore a 324 to 4 inches and use a standard bore 371 piston to make a 345. Yes, the 371 pistons will work, since Olds kept the compression height of the piston the same and raised the deck height of the 371 blocks to compensate for the longer stroke.

[Mike B]

But could I bore the 56 324 to 4.125"? A 1/4" bore.?

Mike

[ZZ-IRON]

good to know Paul, gotta check my 371? to see if it really is one the guy told me it was a 371

Mike

After 50+ years of cooling system corrosion? I wouldn't, if the block were mine.

[Mike B]

That's kinda what common sense was telling me, but I wasn't sure if there is enough cylinder wall there to bore that big. Thanks HEATHEN.

56 Olds Rocket 88 324 HEADERS? Are they available? This is a stock bodied car, not a Rocket shoved in a coupe or roadster.

I have never seen them, but I am building them w/ a buddy of mine this winter/spring for my 57 Olds w/ a 371 and his 55 Olds w/ a 324. It does not look like an easy task...LOL...it will be my first set. The hard part of sourcing flanges is done.

[REM/Mo]

Where did you find the flanges and how much$$$?

[cadillacoffin]

all i need is a gasket or template and i can cut any flange you want.

http://www.jalopyjournal.com/forum/s...ighlight=david

[mike1951]

I once met a guy who tried to sell me a 53 olds with a "308" in it...was he on crack?
I tried to tell him 53 was the 303 with the highest hp for that engine...but he insisted it was a 308....am I stupid or is he?

[Large_911]

Originally Posted by REM/Mo

I bought them on e-bay, but they look like Victory flanges. I do not recall the cost, but they were not too much. They are not cheap and thin -- nice work. I have a pic in my album along w/ copper gaskets I had made. Headers by Ed makes a beautiful flange for the early Rockets (his site is alive again!!).

[REM/Mo]

I'll bet I can make up a template.
I think the gaskets are singles for the individual ports.
