aluminum heads

That is the formula for determining the required CFM of any engine:

CFM = Displacement, times, RPM divided by the constant 3456

Thus if Brian is running a 302 CID engine and only wants to turn it 6500 RPM's then all the carb he needs is 568 CFM - By doing this he will increase the throttle response of his engine, with the added benifit of the carb being able to meter the fuel much better because of the high velocity through the boosters.

Thats why I suggested the Weber/Mikuni type carb - because of its higher adjustibility!!!

I don't have a 302, it's a 351w. I also don't have a problem with low end power, it's the high end my engine needs.
