Re: stock chevy 292 with 4 barl intake
old hot rodder math is to double the cubic inch displacement of the engine, so a 600 cfm carb should do the trick, but I think it is over kill. You will get better throttle responce from a smaller 500 or 550 carb unit. When I plug the engine specs of my vortec 350 into a comuter program I have it tells me that a 600 cfm carb is all I need.
