Well you probably wouldn't believe me if I told you but this piston has close to 290,000mi. on it. I only removed one to measure the top compression ring to top of piston so I can get the right pistons. Bearings don't look bad either. Haven't looked at the mains yet.
Bore is pretty dirty/smudged but "clean" in the machining/hone sense. Doesn't seem all that bad just evenly worn. L-19 or 625s will distort those walls though if I throw these back in. So .020" is the plan.
