360 crank knurling?

Yes. Cummins did some of the crate engine and short blocks and I think a shop here in Michigan did some. Maybe Arrow Racing Engines? I forget. Not sure who was first, if there was overlap at the same time, or if there was any more doing them.

Mine had a strand of metal from a wire wheel stuck under the head of one rod bolt. Took it apart and also found an extremely tight cam bearing. The bore was under size from spec from when it was originally built, but it was not fixed when they made it into a crate short block. That was fun.
