Cam wiped out, what the hell did I do wrong?!?!?
So improper break in combine with a too aggressive lobe for a street motor--IMO. A cam like that should have an idle speed of min 1,500 rpm. That is another thing, slow idle speeds can kill cams. The slower the cam turns the harder it is on the lifters and the less oil gets thrown up from the crankshaft.
Real race cars "idle" at 2,500 rpm's. Race cars run cams like this one, not a street car-again imo.
I would clean everything up and email-call Comp Cams and plan on getting a custom cam made and let them pick it. Explain what happen and use break in valve springs next time. Hughes should make it more of a point how to run a very aggressive cam like their grinds. I am sure Hughes cams will squeak out the most power but there are compromises to be made-like fast idle speeds.
