Default Need help identifying a cam
If any of you guys can help me ID what engine this cam is from that would be great. I've searched for quite some time but can't find another LS cam with these markings. Thanks

Stock GM LS7. Stock camshafts had that barcode at the bottom. The bottom row of numbers is the last 4 digits in the part number:

Not to steal the thread or anything but I was wondering the same on my stock cam. I could not find any info even using the last 4 numbers. Its a Gen4 LMG 5.3. I would like to know the specs on it.

Quick Google search of "3207 GM cam" brings up a few threads on it being a L33 cam. Hope it helps.
