When was the last time you saw one of these (mystery race engine purchase)

I had a chance to mic the pistons. All of them come in at 4.3693-4.3704 with the exception of #4 (4.3665) amd #3 (4.3674). I think I'll be good to go between .005-.006 PtW clearance.

The next step will be cylinder bore inspection using a dial bore gauge. Hopefully a few strokes of the hone, two pistons and a set of rings will take care of the short block.

I didn't notice where two pistons were damaged. If they are just too small for your liking just have line-2-line coat them and be done IMO. You're doing good work as usual!
