Alright let's dive right into this. My block is stamped 2222, so all my bores should be..74.98ish mm , they currently measure 75.050-75.06mm , so the engine has some wear on it. I cant even see the hone marks anymore. I have a new set of pistons that measure 75.02 mm. Im on the fence here,I seem to be right at the threshold of needing to have the engine block bored, I know the clearance stated is for NEW from the factory tolerance. What would you all do,I have the engine out everything stripped down,so if I were to get it bored nows the time. Just have to get new pistons then take it all to the shop. This by the way is the same motor that LOOKED like it was religiously taken care of,until I got all the way into the crankshaft to find a missing journal bearing. So the crank is being replaced /fixed. So I'm really tying to decide if I should just put the block in the shop,or Roll on with "standard" pistons. Any thoughts?
