Cam cores come from the US, it was discussed here within the last year.

Cam cores are hardened BEFORE they ever get to the cam grinder. Not after, unless you are talking about nitriding.

Chrysler blocks are well known for having cam bearing bores that are smaller than spec minimum, also having a certain amount of shift from the stress relief of daily use.

If you try three cams and two fit and the other doesn't, then there is something wrong with the one that doesn't fit. Could be bent, could have the bearing journals oversize, etc.

It should be possible to straighten a camshaft a couple of thousandths, but that's one more step. A person does not expect to have to straighten a brand-new cam or crank.

Comp gets a lot of blame on this board, and I think it's too bad. They sell more cams than about everyone else put together. If their failure rate is the same as the others, they will naturally have more complaints than any other. And, with the reckless way that charges are thrown about, it's a wonder that anyone has a business or even cares to build things for Mopar enthusiasts. We have a tendency to bite the hands that feed us.
