Hello, I am new to the forum and finally acquired a 2002. I am Mechanically inclined but not yet a mechanic. I purchased a 1976 2002 with a window in the block made by a piston rod. I rolled the dice and bought a seized 1972 M10 with an E12 head hoping to salvage what I could and then swap blocks, crank, pistons, E12 head, etc. So far it looks like the seized motor is only seized because 2 pistons are rusted in the cylinders. All the bearings/journals look good and there was no metal in the pan. Two questions. One, if I can remove and restore the piano pistons is it doable to put them back in the '72 block and then use all the good '76 parts on the '72 block? This would include everything from the complete '76 except for the head, crank, and pistons. Second question is should I expect any issues from the higher compression pistons and the E12 head? Im also using the '76 4 speed trans.
