I need help identifying these GSC cams. Came out of an Evo VIII. Are they S1's, S2's or something different? Would be nice to know what I got and their duration, lift ect... Any help would be appreciated. Thanks!

 

Call GSC!!!

 

There S1 cams S2's have more yellow paint strips not blue all over.

 

why do they say 2 on them tho?

 

I dont recall my S2''s having "GSC" marked on them. I think one of them had a "2" on it though. Are those older GSC Cams?

 

Is that steve rossbach on the newspaper ?

Give Greg a call at GsC and he should be able to give u an exact answer buddy ...

 

Thanks

 

Solved! Got w/ Greg @ GSC, he asked for the grind code which is in very fine print opposite of the JH93 stamp. It was stamped PPA which he said is the grind code for S1's. So...
PPA=S1
PPB=S2
PPC=S3
Maybe this will be useful for someone else down the road. Thanks for the help!

 

did he tell you how to identify an s2 cam?

 

Yes , it's in my post.

 

thanks.

 

Would be nice if they would just put the part number on the cams.
My new GSC S2 274 cams are stamped PPG

 

This is not correct. these numbers change as to the batch that they are run in.

 

 

It might be best to call GSC as the PPX changes for each batch.
