I changed out the oil pump and dizzy so I can put on a newer carb. The car is a 54 capri. Trying to figure out the cfm for it. I've been looking at 500 cfm 4 bbl. Is this the best choice? Engine is stock, no high performance parts. Would 600 work okay? What size was the original carb? My engine didn't come with one.

The original carb was a 4 bbl holley 2190. So the intake is 4 bbl ready. I found out that the original was 335-375 cfm. So now I'm trying to find a 400 cfm, preferably newer that i can install using an adaptor plate.

Brad, you’ll get more responses, but I think this is worth looking at. You’ll need someone more knowledgeable than me to say it’s the right adapter.

Summit also has a line of carbs that are well spoken of, I think a couple members here have used them. This 500cfm might also fit the bill.

I assume you’ll be looking for good low end response and drivability, they might serve that pretty well.

Thanks miker. I just font want to put too big a carb on it. I understand the car will run bad and terrible mileage.
Just saw the carb at speedway. Pricey
