“Wiped Cam Reveal”

Here’s one that isn’t posted often here. Slow rate, fast rate, obsolete up to modem lobes, old vs newer cores, QC or lack there of, etc. So who has wiped a cam? What brand? Give the specs as best you can. How soon after install/break-in? Don’t be bashful or embarrassed...not looking for theorized reasons or excuses. Simple what and who. Just might be interesting to see brands and types. New, old, slow, fast, hyd or solid doesn’t matter. My son had a Comp Cams 280 Magnum hyd in a 360 lose a lobe after two years of ownership (bought it with mods already done) and lots of use.
