    Ho ya, I've seen stroker #s up in the high 400's for both HP and Torque!

    You can make way more power than that, but how much depends on if you want it to be streetable. With the right cam and heads, I'm sure that 700HP could be made with a 383. At least for a while... [​IMG]

    These guys are right on. You can always make as much power as you want, but you always pay the penalty one way or the other (price and driveability).

    You should be able to make about 400 reliable HP (at the flywheel-If he's getting those numbers from the rear wheels, he's got a real monster and I want a ride!) and still be able to drive it everyday. Get a good low end type grunter/torque cam (Comp Cams Extreme Energy grind is pretty nice--but go with your favorite cam builder-same kind of pattern) and some decent flowing aftermarket heads (don't get the big hoggy ones--the smaller ports will build more torque--GOOD thing in our heavy beasts) with a solid built short block and you should at least be in that neighborhood, but reliable to boot.
