Well i got out my vernier caliper today and measured the cylinders as far down as i could, The pistons are stamped with a 4 and have number Cam H-8 357791-R1 and looks like they are in good shape. I think they are the 4 inch piston? The cylinders are all pretty close all the way around. Farthest one off was .003 out of round. but all measure right around 3.980. The pistons do have some wiggle in them all the way down the cylinder. None of the valves are stuck on the top end but have a TON of carbon buildup so im going to take those apart and clean them really good. As for the bottum end, i didnt have any play in the lower bearings at all. Everything looks to be in great shape other than the rings and head. So should i just use a ridge reamer and hone the cylinder with a fresh set of rings? Thanks!
