I never lost but one cam and lifter set in 40 years of wrenching and I still blame that on the butthead owner that I put the cam in for. I guess I was on the right track 40 years ago....LOL

Put together 3 small block Chevies, a 351W Ford, 2 318 Chryslers, a 330 Olds from 18-25 years ago all with STP, (stock rebuilds) all ran for years after that.Built the 455 in my 66 wagon with STP on everything in the engine in 1987. Has 100,000 miles on it now and still runs good with good oil pressure. Putting it in another car (after I lower the compression a little with different heads) to make way for another 455 Mr P body is building for me. Dont seem to have time to do these things anymore, and I doubt on my best day I could do as good a job on getting the most out of the engine as he could. I think a lot of cams are burned up with excess valve spring pressure on break in as well as the junk oil they have nowadays.
Lousy oil, lousy gas(e10) and lousy policy making by the govt.
If I put an engine together today, I wouldnt hesitate to use STP or Lucas for assy lube. And talk with the cam manufacturer about the proper valve spring pressure to use with it.
