318 piston ring gap
Ok, I took a piston out today. Factory rings have about .025" ring gap maybe a tad more. Side clearance calls for .0015-.004" My smallest feeler gauge is .006 and nowhere close to being able to squeeze it in there. My new rings have about .017" end gap, so with a quick deglazing I will be fine. The bearings still look brand new and the crosshatches are very noticeable.
Since the lifter valley has gotten dirty from sitting w/o an intake, I'm going to tear it down and run it to the machine shop to have them give it a bath and ball hone it for me. Piston skirts look great too with minimal marks.
