Coolant leaking into 318 cylinder 8

I am not saying you are wrong. I am saying, I don't want to play this game twice. And I am not a big fan of fool me twice. I really do appreciate your advice and perspective. The story is a lot longer with the entire project than I will bother you with.

I have a block from a running engine, and am already on my way down that path.
Your doing the right thing. Those mid 80s 318 blocks are crap anyway. Almost every one I have looked at are cracked on the deck surface to those open head bolt holes. They are THIN. Sell off those cheap rebuilder .060 pistons and bore the replacement block the min required to clean up.
