I have a steel gear from MSD on my dizzy aswell and it looks exacly as you discribed. Satin black parkerized looking finish.

For your cam gear to wear like that it seams that it was way softer than the dizzy gear.

Makes me question if the cam was realy billet steel or somthing softer.
Or may be the dizzy gear was way harder than it was suppost to be.

To much cam end play or distributor and cam mesh to tight along with wrong materials.
