Technical Cadillac 331 to much carb?

I really like this intake and carb setup but I’m wondering if it’s to much for my car. It’s a 1955 Cadillac with the 331. I’m also wondering how much trouble I’ll have with the hydromatic trans trying to get it to shift right with this setup



I copied this from his add

The carbs. Holly 2100's) are better than Stromberg's for this application. Why? A Stromberg 97 flows 160 CFM. A Holley 94 flows 180 CFM. A Holley 2100 flows 205 CFM, giving this intake a whopping 820 CFM

Depends on what what rpm, if she spins to 8000 it will be fine.
I think those are more show than go.

 

Great looking set-up.
Your 331 would run just fine on one of the carbs, cfm -wise, but where is the fun in that?
You will need to run the 4 together in order to balance the fuel/air to each cylinder so just go easy on the throttle.

 

Get a UniSyn from Summit. A great tool for multiple carbs...

 

Yes, it's over-carbureted, but I don't think excessively so. We routinely put 2 500 cfm 4 barrels on a SBC and don't think twice about it. That engine would never use all 1000 cfm. As long as you use the proper jet sizes the engine is only going to take what it needs.

You will however have a hell of a time getting that to work with the Hydramatic, which is very sensitive to TV linkage adjustment. Not impossible, but it will take some careful planning and some head scratching.

 

You'll have to go to a mechanical choke also.

 

After you adjust the 2 barrel CFM rating, which was dome at 3.0 inches of vaccum, to a 4 barrel equivalent done at 1.5 inches ( divide the 2 barrel number by 1.414) your overall CFM rating becomes less daunting. So you are at about 580 CFM total. I run 94s in multi-carb applications because they are typically more affordable. And if you don't mind going a bit crazy, you can tune a bunch of stuff. There were many models. but the average 94 flows more like 150-160 CFM, but if those are 2100s they are the big ones at 200 to 210 CFM
However, the 97s with the mechanical fuel enrichment is a bit easier to tune, so perhaps better to many,

 

With 4 accelerator pumps, you won't be needing any choke ....

 

Setting up a bell crank for the hydro shouldn't be too hard..

 

I have seen some bell-crank assemblies that were works of art.
Up, down, forward, back and around corners all doable with the right pile-o-parts, not forgetting changing of the ratios

.

 

It might be too much for your staff, keeping it polished.

 

Eldorados. came with dual quads and 3 2's in 57 and 58, should work OK, 4 x 2 is the same as 2 x 4.

 

Great bunch of information here.

 

I used a UniSyn for years on my NA Corvairs.

 

You will also find it will have a VERY touchy throttle.
