Okay, I know it's not an SC, and not even a ford for that matter. I pulled the gen5 502 BBC out of my boat after it spun a main and couple rod bearings. Does anyone know a shop in the IE or San Diego that does Align boring? I need the mains bored, and the block and heads decked.

Seems like everyone can hone the main journals, but no one can bore them.

I've come to the conclusion that the last builder used the wrong size bearings in those two rods. The main bearings didn't look TERRIBLE for 250+ hours, but check out the groove in the main cap. That groove is identical in the block.

This is the two rods that spun. They were machined .050", and used stock size bearings... :rolleyes:
