Prefer to use a 350 block .030 over,not interested in finding a 327 block if I don't have to. I have the forged,small journal 283 crank with it's 3.00 stroke,5.7 in.rods. Can anyone tell me where to find pistons that will fit or would there be a different length rod to use that would make it easier to find pistons? Would prefer to use a hyperutectic slug if available.
