Camshaft identification

I have this cam that came out of a 360, I am trying to identify it. It has DRV3 stamped on the end, and some other numbers. Looks like D2 and I-5 under it, and one the other side it looks like C2 and either VS4 or V64 under it. Googling drv3 camshaft came up with this. Can anybody help me with this?
