No, I think it is the first build on a 77 block because it is only .020 over.

The valve train is non adjustable for this setup.

The .484 cam that was in there did not have this trouble.

The other lifters showed signs of wear, but this was the only one that looked like that.

Thanx for the help, though. The cam did make good power. I'll break it apart and see how the rest held up. Those metal shavings had to go somewhere.
