Well, the good news is the machine shop didn’t seem very concerned about the crank, or the cylinder walls. Sounds like a honing will do for the cylinders, and he’s going to measure the journals and get back to me. His guess was that the material on the crank is Babbit. I didn’t get to pulling the cam before dropping it off, the shop is gonna do that and check the bearings there.
It’s funny, first thing he said was “Wow! Never seen THAT before!!”
