OK so I have the engine out. The bores with crosshatch appear to be too big. I can see most of the top compression ring. Plus I have a crack or foundry error in #2.
So I will have a set of Diamond coated 4.350” pistons and Manley H beam 6.86” rods for sale.
Since I will have to bore the engine to clean up the cylenders, I will have to buy new pistons, might as well go to a 7.100 rod to ease the rod ratio with 4.5” crank.
