OK maybe that's it. Do you think wiseco would build me 2 pistons or will I have to buy another set of 8? A member here is sending me a 73 360 block with the 4 bolt main conversion short fill line honed and a 4.040 bore. If I can get just 2 pistons made I can get this back together pretty quick at low cost. If I have to buy a whole set I will start on my big block project.
