Tony, a 496ci at 7000 max rpm at 100% VE only requires 1004cfm. Chances are your not at 100%, average could be somewhere in the mid 80's range which could be even less cfm needed. Try this link for carb sizing. You can plug in a lot of different numbers to play with...www.4secondsflat.com/Carb_CFM_Calculator.html

K thanks a ton.. I already bought a 1050.. which as we know has the same throttle plates and bore as the 750 dominator.. so I know I'm atleast on the higher side of the ball park.. glad I didn't buy a 1150 cause that would have been too much.. thanks for your help.
