Cam wiped out, what the hell did I do wrong?!?!?

.600+ lift say 30 years ago was unheard of for anything but a race only motor--that was torn apart after a few races. Why things should be different today I do not know. True, we have computer program camshaft grinding machines but.

And yes, the more ratio-the more pressure.

Your in solid roller lift rates, imo.

I have to agree with those who say this should had been a roller camshaft. Not saying its needed on the street but if you want .600+ lift--even during break in, well roller is your answer. Not sure if even hot roller cams should use special valve springs for the first hour and stay under 4,000 rpms?
