Canzus I've run larger carbs on 2.8L V6s, and have tuned 4 cylinder Pintos with 600cfm carbs,
a 750 would be in the ball park for a stock 428... My Capri is running a 750cfm carb,
and it's a little 302 ci V8...

sbchevfreak Yes, 450 cfm is way too small for your FE. Likely 750 cfm would be more in the right ballpark, as IIRC the afctory piece was rated @ 735 cfm.

Carburetor too small??

I have a 68 galaxie, with a 428fe
I recently had a holly list 4548 put in and I feel like its choking my engine and the idle sounds too slow. Is it possible 450 CFM is too small for my engine?
What is the recommended size I should use?
