Just did a quick search on the Comp Cams site to see if they refer to the cam material and hardness in their spec pages. Could not find anything.

By the picture it's easy to see that it's a billet material cam. Did any of the information they sent with the cam include the material specs?

It would be real interesting to have the hardness tested. I would do it on the shaft area between the distributor gear and the first cam lobe. Then I would test it on the cam lobe surface also.

It could be a heat treat issue. If so, it would not have mattered what gear was used, it would fail regardless.
