Generation IV Internal Engine - Need help to identify this GM cam

Can anyone help me identify this OEM GM cam?

The numbers etched in the end are:

3063
S 13
9208

I've Googled them and searched the forum and found nothing.

You should be able to figure it out with a pair of calipers. Just measure the lifts and compare the numbers to what cams GM offers. Dont forget to multiply the lift number by the rocker arm ratio ;)
