April Bang-er thread 2011 OOOGGGAAA BOOOGAAA

I spent the last 4 days at the lone star round up. It will take me at least 3 weeks to soak it all up

 

Yes, with a little fussing both the A intake and exhaust will work on the T. My neighbor was the last "King of the Hill" at the long beach hill climb and he did it with a flat head T running a 4 barrel carb on an A manifold. 'Course most of the hill climb cars were built to do one thing...run wide open up the hill. By the time my neighbor won, overheads were banned from running.

 

trestles126 very cool RPU. What intake manifold is that?

 

That's what I was thinking, but was not sure. I think I have to agree on the 48's being too much. My engine will run a stock '26-27 crank, 3/4 race cam and a "Z" head (comp ratio 6:1). I am having it ported/relieved..but I'm not sure on the valve size yet.

Yes, the flywheel will be relieved of magnets and the mag windings.

A close friend and I built a T speedster with an identical engine running a Holly "94". The original .049 jets ended up being way to small .....059 jets did the trick, and I probably could have gone a hair bigger. Not sure if that means anything though...

 

Ok ..may be it's me but if this is a gravity fed fuel system how does the rear carb get it's gas.................??

Do you think the new engine with a stock '26-27 crank, 3/4 race cam a "Z" head (comp ratio 6:1), light flywheel and bigger valves would run with twin 97's?

What about jetting the 97's down a bit? Do you think I'd be better off with twin 81's?

 

probably better off with 81's or 94's
they are the smallest cfms
why not a single winfield or lz
tk

 

That's kinda what I was afraid of, been trying to find 2 81's....haven't been able to for less then the cost of a first born.... Been looking for Winfields too...same deal.

I could run twin 94's, but I like the look of the Strombergs and I only have one...that's not in use (its also a late model). The other 94 that I have is an early, but its on a buddy's speedster, might have to steal it back

I also have a pair of single barrel Zenith 28's....just don't think they would be right though...

Anybody have another early 94 they would be will to part with?

Also...if I did run a set of 94's (or tried the 97's) what jet size should I use?

 

Are there any hot rod or restoration magazines that have good four bangers articles?

I have some 94's in the shop, but as I have never messed with a 94 how do you tell old from newer? What I have would just be cores.

 

Great carburetors...messed around with them quite a bit. I like the early models myself.

There are 5 different generations of the 94:

1939-41: has "Model 91-99" cast on side of float bowl.

1942-46: has "Model 21-29" and "Ford" script cast on float bowl

1947-48: has "Model 59" and "Ford" script cast on float bowl

1949-51: has "Model 8BA" or "8BA" with "Ford" script or "FoMoCo" cast on float bowl. (Also has vacuum port in carb body for vac advance)

1952-53: has "EAB" with "Ford" script cast on float bowl. (Also has vacuum port in carb body for vac advance)



There are a few generations of "Aftermarket" versions as well:

1938: Has "Chandler Groves, Co. Detroit U.S.A." cast into Float bowl.

1932-51: Has "Holly 2100" and "94" cast into Float bowl.

1951-52: Has "Model 7RT", "94" and "Ford" script cast on float bowl. (Also has vacuum port in carb body for vac advance and cable choke. Pick-up only)

1939-40: Has "Model 92" and "Ford" script cast on float bowl. (Actually a Holly 92 used on 60 HP V-8 only)

 

WOW....
Thanks for the info Mr T
I have only played with the 94s
I am to cheap to spent 200 - 300 bucks on a good core when I got my last 2 59s for 125 each all rebuilt

 

No problem! Every so often, I get the chance to use some of this info that is taking up space and collecting dust in my brain

I know what you mean, the "94's" are getting expensive these days....Forget decent Stomberg "48's" "81's" or "97's"....I just couldn't stomach opening my wallet for some of the prices I have seen them selling for. I count my self lucky that I paid $150 for 2 complete and nice "48's" last weekend!

 

i picked up an 81 that was missing a top for $75 shipped
i almost did a back flip
the tops are the same from carb to carb, so i got a donated top from a friend and now i have another complete 81
tk

 

At the lone star round up there was 2 81s with rot holes in the bowls for 150 each. I think that was the same guy that wont's 500 for a alum intake with holes drilled in the bottom and some crusty straight pipe header

 

The "81's" are starting to get REALLY hard to come by...let alone for a decent price. They were really popular with the early midget racing crown and they only made 'em from 1937-1938 for the 60 HP V-8s.

There are certainly some people out there that there stuff (like an intake butchered with a hack saw in the 1950's for some home made application that was done poorly) is worth millions when it's actually junk. There are also people who have good stuff, know what it's worth and price it fairly. I picked up that Burns intake for the T for $250...a screamin' deal and a super nice guy to deal with.

 

I have 97's that have " $5 " written on then in soapstone that I bought in the early 80's when nobody wanted that crap. I also have a 2x6 set up with 97's for a small block that I traded for a camshaft.

I also paid $800 for 4 rebuildable 81's about 2 years ago. It all balances out eventually.

My motto:
If it is a good deal, buy it.... Even if you don't need it now.


.

 

I am going to show my ignorance; do the numbers mean anything as in the cfm size? Like smaller number, smaller carb?

 

$5.00!? I WISH I could find "97's" for $5.00 a piece!

I have a matched set of 4 "97's" and a super rare 4x2 intake that was made here in Portland, OR by a local speed shop. They estimate that only 6 to 10 were ever cast (in 1951 and 1952) and of those, only 2 survive today...mine and another across the river in Vancouver.

Both the carbs AND the manifold belonged to my Grandfather and were on his A-V8.

I know it's not a 'banger...a lil' O/T, but what the heck



I would HATE to buy this thing now!

 

No worries! There are no stupid questions, gotta learn sometime!

The names "97", "94" and "81" refer to the venturi size:

Stromberg:

"97" = .970" Venturi

"81" = .810" Venturi

Holly:

"94" = .940" Venturi

The Stromberg "48" is different, as the nickname stems from the jet size of .048

 

ah, I was sort-a right. so the 48s are bigger than a 97 then?

 

Yes, The Stromberg "48's" are bigger then the "97's"

"97" .970 Venturi .045 jets 155 CFM

"48" 1.03 Venturi .048 jets 185 CFM

"81" .810 Venturi .043 jets 135 CFM

Holly:

"94" .940 Venturi .050 jets 150 - 190 CFM (depending on the model)

 

I posted a reply on the March banger with a picture.I used the original throttle linkage that is mounted on the back of the engine and then fabricated a bell crank from a flat bar.

I posted yesterday on the March forum.

 

Someone told me that the bottoms or the tops of the 81's and 97's are the same. I can not remember which is which. Maybe some carb expert will see this and tell us again. Maybe the guy that told me this was wrong.

 

The top castings (air horns) on the "48", "81" and "97" are all the same. The base assemblies on the "48" and "97" are the same (marked EE-1), but the base for the "81" is different (marked EE-7/8). It is smaller with smaller throttle plates.

 

crazydaddyo....i like your new picture..you dirty dog
i saw the add 3 minuites after he posted it and started to p.m. him and stopped
as you said below if its a good deal buy it
lol
tk

 

Best motto EVER! ..Great advice too.

 

So if I run a single 2bb on a model a what carb would operate the best with out any major changes done to the carb. Also what is a good choice on a single bbl down draft carb? thanks.
