Putting a new cam in my 360

Thanks for that. RPM varied for sure, but the lack of high-viscosity assembly lube is what caused the issue I think.

Absolutely. Imagine how hot a cam gets with no oil at 2000 or more rpm with metal on metal contact. As an example. If the circumference of the lobe is 1.5 inches. Then the lifter traveled 250 FEET on the lobe for just one minute at 2000 rpm. Metal on metal contact. For 250 feet. Not pretty.

You can imagine what that's like.
