My first thoughts were a seized distributor, and the cam wiped out the distributor gear. Or the cam locked up (bad bearings), wiping out the gear. Or the oil pump locked up, distributor came to a sudden stop, and the cam wiped out the gear.

I have no idea.

I would make some inspections to confirm this diagnosis before proceeding, to be sure, but as @cruiser54 indicated, probably time to " break out the tool kit"
