I've spent over a half hour google'ing and reading goofy posts and even got on GM's site that I typed in the #'s and NOTHING came up..

I have two cams.
--Cam 1= 241 cpc bc 1 ---Supposed to be a LT1 cam but would like to know the ACTUAL specs, and not "DUDE.. That's the same one I got!!!" or "Yup, It's aLT1 cam alright..."
--Cam 2=(at the back of the cam, by the plug) HOW IT'S ACTUALLY STAMPED!

Thank you for your time.

Best guess I can offer is sometimes a pair of 4 digit numbers like you say is on the second cam can be lobe numbers. I can tell you searching Comp's 2010 catalog neither of those is a Comp lobe number though.
I don't know if that can help or not, at least now you have some idea of what numbers could mean.

Can you post pics? Not that I think anyone can visually identify cam specs but maybe the way something is stamped or etched could be familiar to someone.

It is a GM Performance LT4 and having a custom grind done to it..
He put it on his "cam doctor" and checked it against GM's catalog.

Thanks Anywho.
