Just got my 360 torn down. Looks like some rather severe scores in the cylinders. I noticed some minor scoring on the bearings as well. This is the first bottom end I've done. Obviously I'm replacing the bearings and having the cylinders bored.

Since I'm rebuilding it anyway, could someone suggest a piston/ring combo that'll help me on my way to around 300 HP? Looks like the bone stock mid 70s 360 only made around 155 HP. I don't mind spending the money, since it'll come a step at a time. I realize the top end makes more or a difference than the bottom end, I'll get to that as money allows.
