    The Holley Red should be more than enough for up to 650+/- horsepower. The formula for determining flow (in gallons per hour) is as follows:
    HP/2 = lb/hr
    lb/hr / 6 = GPH
    multiply GPH x 1.15 to provide a margin of safety

    So 650/2 = 325
    325/6 = 54.166
    54.166*1.15 = 62.3 GPH
