    Question Carbatooter cfm

     



    OK guys,
    I'm running a mild 406 w/flat tops, 76cc heads 1.94x1.60, Comp 280 mag. cam and a performer rpm intake. What cfm carb should I run. I've heard a rule of thumb is cubic inches x 2 is the cfm you need to run. ???

    A 750cfm would be just right. Any larger and velocity may suffer. Should give you all the power you want.
