I was told this was a GM Performance ZZ4 Cam I have.

Is there any way I can tell with just the numbers on the cam?

All it has is:

071AC
035 R

I know the part number for this cam is 10185071

Im guessing the 071 on the cam coincides with that of the part #, but that could just be a coincidence and me be way off.

Any help appreciated.
