LOWBUCK rebuild options??

as fastback 340 says start with a sound motor, if you plan a rebuild from the crank up then compression is the #1 factor to making H.P. and the hardest to re-do once its in the car. If you dont want to buy pistons then the mopar hot tips book recommends a .020 to .030 mill on the heads to raise compression from .4 to 1.1 compression increase. From there build as wild or mild as you want
