Honed the cylinders today, they turned out great. Also cleaned up the pistons got all of the rings swapped. Not sure how common this is on these big blocks but almost every 1st and 2nd piston ring broke as I removed them, even when trying to be careful, not that it mattered. I would guess maybe since it was running poorly before and already had a couple others broken that they all were just brittle. After looking closer I decided to replace the rod bearings, they aren't grooved or anything but once I cleaned them up they show some discolored spots, so might as well do them while it's apart. Got the rest of the block mostly descaled and degreased as well. I cleaned out the oil pan and found a little filter screen, guessing maybe part of the oil cooler system?
