I've got a '70 Vette with a 406 in it. The motor is fairly warmed over with heavily ported aluminum AFR heads, roller cam, headers and Edelbrock intake w/ 750 double-pump Holley.
My question is this: if the heads are ported to flow somewhere in the neighborhood of 275 cfm per cylinder (intake), shouldn't I put a dramatically larger carb on since in total the motor is capable of flowing 2200 cfm? Should I have a carb (or carbs) that flows at least half this cfm? Thanks for any ideas.
