D series bottom ends...
Use the Z6 block for the lower compression as Eee Pee stated...there are several people on this board pushing 250 WHP on stock internals (with a shitload of tuning though). If you want to run more than 10-12 psi, i'd suggest getting forged pistons, eagle rods, arp head studs and rod bolts, and think about sleeving your block.
