Thanks for the responses.. I have a 1250 dominator and have heard it is too big. How much power/ET do you sacrifice running a carb that is too big? Also, what intakes do you guys like for a BBC making 825 HP?

carb
I like a super victor intake.Call pro sytems and ask if the 1250 is too big.A buddy of mine just got a pro systems carb and they recommended a 1200cfm for his motor and it is a 540.He had a 1050 quickfuel and put the pro systems carb on and picked up about a half a tenth.
