I have a 750 cfm carb that bench flows almost 1000 cfm. This carb was recommended because I am more street than strip with my 496 engine. Keeping the air velocity up through the carb will make it more drivable vs. a 1050 dominator. I have no personal exp with a 1050 dom but was told that is best for strip only, wide open driving. Won't be very street friendly.
