I was wondering if any one knew if my cam is stock or upgraded. On the rear end of the cam it is stamped with SDC2 and f 3 written with a paint pen or something. Cast into the cam between some of the lobe things are C2, E12, and EP40. Does anyone have any clue?

Thanks!

The Nissan cams were pretty much all identified by a single letter stamped on the rear end of the cam. So what you have does not sound stock. I personally have no idea what it might be.
