I wouldn't say I've ever snapped a cam, but I have wiped 3 cams total. When dealing with flat tappet camshafts, if at any point the lifter stops spinning in its bore, your f***. And there are about a million things that can wipe out a big block cam(bad break in, low oil pressure, burrs in the lifter bore, idling below 1000 rpms even once, and many more!). For every 1 professional engine builder that says it's never happened to them I'll show you 100 builders that have had it happened MULTIPLE times. I actually don't know what happened, this lifter was smoked and two others had stopped spinning and started the lobe wiping process, but it cost me all my bearings I'm sure. Yeah, another rebuild!
