New gear on the cam failed. 20 minutes of run time, backfire and quit. The distributor gear looks fine, the cam gear furballed. Crown gears. Did a redneck hardness test with a scribe. Dealer gear didn't get scratched, Crown gear has deep scratch.

There are 3-4 different known "flavors" of cam/dist gears out there. Each have a slightly different hardness and pitch to the gears. They should ALWAYS be replaced in matched pairs, otherwise the mesh may not be right, and you end up with one eating the other.
Bulltear has new AMERICAN MADE sets. Get them at the e-store.
