My big block left yesterday, and I got some news back today. The crank is out and all the main journals look great. I think maybe since the rear main was installed backwards, for the period of time it ran before I owned it (the PO said maybe a thousand miles since it had been rebuilt) it likely had an oil leak. A bad one. .. and/or it starved that rear main bearing of oil because it simply couldn't hold pressure. We're hoping the crank will clean up at .0010+ but we'll see.

We're going to tank the block, test it and rebuild with all good stuff. New rings, etc. It will get there ..
