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)

a good start for anyone that is interested in these motors would be to read this thread in the Tech Archives.

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.
