Numbers stamped or etched on the end are the only identifiers to tell you what spec is ground on the cam, if you can find a match to somebody's catalog.
The numbers cast into the side are all just cam core identifiers and have little to do with what profile was actually ground onto that blank.
The "CWC" is identifier for Campbell, Wyant, & Cannon , the Michigan foundry that cast the cam blank, roughed in the lobes and bearing journals, and either then sold as a core to a cam grinder, or finish ground it on spec for a bulk customer. The rest is just foundry info numbers cast into the blank.
I thought the "115213" might be a Howards Cams number but no luck there. Also strikes me as maybe an older Crane Cams number.
Any idea how old it might be??
Beside a search around the net that may never yield results and eat up a bunchh of time....you could just degree it out just like you would if installing it but use the process to reverse engineer a cam card. then you know the exact spec of what you have.
If this is a used flat tappet cam, and you don't have the lifters marked for matching to the lobe they were originally on....then it's a doorstop.
Big risk of it flattening a lobe if you try to reuse it with new lifters.
Bad enough risk to move a flat tappet and matched lifters to another block, since no two production blocks are ever machined exactly the same it increases the risk the cam won't make it through a second break-in cycle.
