Looking to buy a new carb .. but which CFM???? im looking at the proform carb but dont know which one to get.. i got a 383 stroker.. vortec heads ..11:1.... high rise intake.... basic info if you need more info let me know.
I would guess you would need at least a 750 cfm. I am more of a drivability/OEM expert than a high performance guy so check around.

Not tue. Too much carb and you will find your engine falling flat on it's face when you try to take off.
i perfer a 4412 500 cfm holly 2 barrow put bigger jets in it and your rocking i got a vortex pushing 478 hp with it on a dino and a 355 with brodix heads and intack pushing 510hp with a 2 barrow
ive got a 600 holly on my 355 and its plenty enough carb for that id say it depends on whats on the inside of the engine that would dictate it summit or jegs probly could help my 2 cents
i would go with a 700 or 750, that engine needs alot of air
