Run the numbers, or post em there on the side of the carb body, they are on demand carbs, use as much fuel that's needed, SBC q-jets are around a 650-700cfm max and BBC is around 800-850 cfm max, either or will work on a BBC unless your running s monster

frist thing to do is how bad are the shaft are in base plate. that is the biggest problem with them.  sucking air though the shafts.

Thanks guys i have 9 to choose from and its for a 402 bbc so 750 should be plenty

look  down the primarys, if there is a slight in one or both of the primarys than it is a bigger carb. if  no then it is a small carb.

[hot rod heep]
