Uh, what about it? you left a ton of variables that could make a world of differerence. For example, your "stock regound 69 crank", are you talking about a simple grind and polish say .010/.010 or are you talking about offset ground? big difference. Judging by your rod choice, it looks like a .060 piston, stock length rod, stock crank. What specs are you thinking on the cam? There was no mention on a head choice, so I'd hold off on pistons until you get that figured and lastly have the cam ground to match the heads. As it stands now, there are too many unknows to give you any better advice.

The heads are my old ones that I got from Doug. Pretty bad azz set of DOVE's.

See, that makes a world of difference. The right cam with those heads and making sure the induction is able to feed the beast and you'll have something!
