Not Ranked
So I have the answer to these metal bits - main bearing #5 was about ready to go.  Glad I pulled it. (I don't have pics, just spoke to the builder by phone as I was out of town). Some scoring on the cylinder walls, so will need a cleanup overbore.
Was thinking of going with these JE pistons to keep the overbore to a minimum. Thoughts? Other recommendations?
Also, thoughts on compression ratio for 93 octane pump gas? I have stock MR iron heads. I was at 11:1 before, but the builder doing the rebuild thinks that's a bit much.
