Main bearings. Gonna be a complete rebuild I'm afraid. I hope you can save the crank and block. Those bearing halves/shells came completely apart it looks like. Do you know the status of the balance job on that motor? It might have ate itself up by being out of balance at sustained high revs.

I got away with a new crank and a rebuild when mine looked like that but I did save the block, rods, and pistons with a line-bore and oversize bearings.

Those Fords are tough little buggers. It could be worse, a rod could have let go, or it could be a Por$$$$che.

Sorry to see what happened but now you can rebuild it your-way with a bunch of cool new parts and a complete balance. You know you wanted to anyway, right.
