I'm going to go against some the the grain here and say that cam is compromised and likely 'soft'. The cam in the pic that Fast posted LOOKS GOOD TO ME TOO but, it looks differently 'worn' in my eyes. My buddy bought a solid roller cam from Comp about 6 years ago and the core color between lobes was black like seen. It wiped out in the same manner in a very short time. They all used to be 'copper' color from what i remember until relatively recently. The one solid roller i bought new from Comp around that same era WAS 'copper'. I'm not sure if that is a reflection of the parent cam metallurgy or just heat treat. His newest cam is 'copper color' but was bought from Crane about 4 years ago and has over 3x the use on it so far and looks fine under all same conditions. And for what it's worth his newest cam has a significant increase in lobe intensity.
