You could ask someone to run the quarter mile who has a similar rebuild and use one of those 'reverse' dyno programs that calculates HP based on quarter mile times, and a couple other variables...that would get you in the solar system for a guess-timate.

Some of your equation will also depend on exhaust and intake/carb choice.

My duster runs a .020 over 225, 9.22:1 compression, ported/gasket matched the head, Comp cam 252S, Carter BBD, Super Six intake, with stock Feather Duster exhaust pipe, and it's a big improvement over the stock 1 barrel version, but I don't think I'm over 130hp 'net' compared to the 100hp 'net' that it was stock....

good luck,
