A few years back when I was building the 360 currently in my Duster I called up Jim to have him grind me a roller cam as I used a junkyard 5.9L Magnum short block. I brought up the idea of regrinding the factory cam and he said he doesn't like doing that as it takes off the outer hardened layer of the camshaft material. Sounds like Parkerizing/re-hardening is a necessity more than a nice option. I didn't notice the Crower guys re-hardening the cam after it was ground in the OP's linked video...?
It took Jim a while to find a core to grind a new cam as they were in short supply back then but I was fine with waiting and paying more for a better part which I understand isn't the OP's situation. Cam works awesome btw, put at least 10k miles on it so far and couldn't be happier with the performance. In fact I drove my Duster to work this morning lol.
