I am about to put a set of gsc s1 cams in my car and looking at the ones that are currently in the, they are not factory. They are not hallowed, and the casting is much smoother than stock cams. There is "am 001 805" stamped on the intake cam.

 

Interesting, I would be interested to know what these are!! Keep us updated

 

Sounds like you have a pair of solid, smooth cams stamped with "am001 805" if you ask me.

Lol that made me laugh... But seriously hopefully you get an answer to your cam question.

 

You are exactly right sir. I just verified the part number for hks 264s are am001-intake, am002-exhaust. Thanks to all!
