    I bought a 28 profile with a 454 chevy punched out to a 468 with a B&M blower and 8-1 compression> The person that I got it from has been vague on the hp, one day its 520, the nest its 600. Im going faster than I thought with this boat around 90. Please help.

    What blower are you running, 174, 250 or 420? Do you know what heads and cam youo have? Carbs? I had a 454 Mag, stock shortblock. Crane roller cam, 250 blower, two 750 carbs, IMCO exhaust, on the dyno it made 697.

    How much fuel are you consuming? The HP can be calculated very easily by how much fuel you burn.

    Rk And how many of us can find out exactly how much consumption?
