Hi guys, After opinions and experience on carb sizing for solid cammed 4 bbl crossy reving to 6200rpm. Currently got 650 dbl pump holley, can be a bit flat up to about 3200rpm with WOT but after that, it sings. I understand that smaller carb = higher velocity and more low down torque/throttle response. How small a carb would you go while maintaining high rpm capability??? Would something in the 450-600cfm be more suitable??? Cheers.
