Re: Crane Cams
Here is some info from one of JohnZ's posts:
You'll find "CWC" or "OMO" on many Chevy factory cams - that's the source ID for the foundry that cast the cores. Chevy also used dedicated individual castings for each of their cams, to minimize the machining/grinding required for the final lobe profile, and the "-140" cam was casting #3927141 - the "7141" will appear raised on the rough core portion of the cam. If you don't see a raised "7141" on it, I'd question its originality.
Also found CWC is Campbell, Wyatt and Cannon Foundry...according to PDQ67.
I know I saw what CWC means somewhere posted by I thought JohnZ, but I have found myself wrong on occasion.
