Carburetor cfm calculator

Has stock 2 barrel. Would I be better off buying a performer rpm rather than the performer? It's going to be a mild build, cam probably have a duration of 224*max. Is 9.5 enough compression
Is get a Performer, 600 AFB.
Is 9.5-1 enough, in general terms, probably so, but in actual…. It depends on the cams timing events.
What’s the gear ratio & are you willing to change it out? Are you willing to change the torque converter out?
