A properly built 383 without the super charger should be able to do 450 to 500 hp. What is your guess?

100,265

Then you add roughly 10.5 ponies per pound of boost, so roughly add another 150 ponies, so anywhere from 600 to 750HP but the real test is put it on a dyno, other factors enter into it also, air density, air temps, moisture, fuel quality, even still it will be a gear busting, axle shattering, neck snapping monster for as long as it lasts. Engines like this tend to destroy themselves.

I would think 625 at the crank would be possible. That would be about 500+ at the rear wheels.
