    With good flowing heads, and 2" to 2 1/8" headers it should be able to support atleast a 950, possibly a 1050 double pumper carb.

    On my buddies 421 with unported 235 Pro Topline heads, we run Super Victor with 4500 base and Rupert alcohol 1050 Dominator. .690" lift cam.

    At 2600# plus driver it runs 5.90's with M5 and 6.00 with M1 fuel. 60's are 1.25

    You may get more help if you ask this in the Forum for Carburetion.
