What we were more concerned with was what caused the damage. It is the fact that the distributor gear had 20 years and 90,000 miles on it already? Was it previously worn when I reinstalled it and I didn't inspect it closely enough? Or is my cam walking? Are there problems with my cam bearings?

So those are some real issues I have to deal with I'm gonna mull it over and see what I decide. I'm also going to email comp cams and see what they say.

I agree. But think that you inspecting it would have been 50/50.
These do fail like this. When you put the disty in a motor with different cam, etc. The loading on the gear will be slightly different (in tenths) and a gear that old may not like it.
If I had to make a guess, I wouldn't think cam walk or bearings is your problem, just an old gear.

I would check the endplay either with a dial or feeler gauges between the gear and housing. There is usually way more than spec. I don;t have the tolerance for an L98 but the SBC is .005 - .009 IIRC. (My 67 that I just did had .050 before I rebuilt it).

Shim kits are available. I'd also put in a new pin (for the gear). May come with the new gear, may not.
