Cam Motion cams......
I'm wondering if anyone, besides me, has had premature wear issues with Cam Motion cam lobes? My first one, back in 2005, had one lobe worn considerably in only 30,000 miles. Too much time has elapsed to remember whether it was an intake or exhaust lobe. My second one has several lobes showing some serious wear, especially #8 exhaust, in 43,000 miles. Very happy with the performance of both, but very disappointed in the durability.......

19 years is a long time, and cam manufacture has come a good ways, plus they might have had a run of inferior cores at the time.

True. But that first cam didnt make it one year. Took a 10,000 mile round trip from Michigan to west coast 18 years ago, hence 30,000 miles in 1 year. The 2nd cam that failed was only 4 years old/43,000 miles, so 14 years apart. They could give me 4 new cams, and it doesnt begin to cover my *** busting or sh.. in my engine or engine oil....

Had you gotten back to CM right after either one happened, they might have helped you in some way.
It doesn't sound like you did that, or at least you didn't say

Did you really wait 18 years to say anything or is something resurrecting this for you? If you want durability from a cammed engine, you need to make sure your cam is spec'd properly and that is has gentle lobes/ramp rates. Small cams last, that is why GM does that they do. Wanting durability is not reasonable and the bigger the cam, the truer this is. You also need to make sure you make valve springs a maintenance issue with anything more than a baby cam. The moment you turn a wrench modifying internals, you lose service life. I would have expected a guy that's been around here as long as you to know this stuff.

WOW! One would think any Cam Core would at least wear and resist like an OEM. I realize the higher RPMs would have an impact but still more would be expected from any performance cam. Sorry to hear cause down time, labor, and involved costs are reasons to be upset.

Wow that's an unfortunate turn of events.
IIRC Cam Motion had a Low Lash Solid Roller they'd durability test to ~28,000+ miles or so in a daily driver several years ago.

FWIW - ran an XER Comp Cam (224/224 .581/.581) for 15 years over ~130,000 miles with no issues. Had several sets of new valve springs etc. Properly set up performance cams can have decent durability.
