    Geez Blown472, I would need:
    Bore
    Stroke
    A little more info on valve sizes and port config.
    compression ratio
    top rpm ypu want the hp.
    Then I could run the cam dealio and see what's possible. Not familair with these Ford motors.

    Right combo I've seen 'em upwards of 1500 hp.

    Ok, try this:
    Bore 4.030
    Stroke 3.500
    12 to 1
    6500 rpm
    INtake port volume 210cc
    ex Port volume 76cc
    Intake valve 2.05
    exhaust valve 1.60
    flow intake 310 cfm at 700"
    exhaust 180 cfm at 700"

    Fiat48
    357 inches
    Max Torque 837 ft lbs @4333 rpm
    Observed Hp 984.227 @6500 rpm
    At 100% VE and TE. 94.94% corrected for pumping loses.
    2.687 Intake Port area required (should be attainable). 3.000 is attainable with a SBC for your comparison.
    I'd say add 20% power for alcohol so roughly 1181 Hp.
    Can't do camshaft unless I can get some flow numbers around .462 lift area on Intake and exhaust and also rocker ratio (1.6?).

    Blown 472
    2.150”x 1.300” that is the intake port area.
    1.6 rocker ratio. I will see what I can find on the .462 lift.

    Ok, Fiat, I am looking at a set of eddy victor jr's
    1.28 x 2.10 port area
    .100 64/54
    .200 127/108
    .300 186/140
    .400 234/167
    .500 268/189
    .600 291/195
    .700 285/199

    Remember the plots most important. Also it might like 114 L/S alcohol. Ci does not care. Only concerns itself with filling a cylinder with known factors.
