carb size

Guest

What is the best carb size for a 500hp motor. I have used cubic inch/rpm/volumetric efficeincy (100%) formula and have come up with a smaller carb than expected. I am currently running a 650 carb for this motor which is more than what the formula calls for and it runs great. My car is mainly a street car very little track time however, is my carb too small? By stepping up to a 750 would I notice a difference?

It depends on whats been done to your motor.650 cfm is perfect for a stock or mild motor.750 is great on a built(lopey cam) motor.If you go to big of a carb youll lose throttle response on the low end.
