CWC is the cam core company that made the cam stock before it was sold to a camshaft grinder. They make cams for hundreds of different cam grinders including GM. Unfortunately, that won't tell you who actually ground the cam and the number could be a random stamp by just about anyone who grinds cams. Tough one to decipher thus far?
CWC = Campbell Wyant and Cannon Foundry
