bought some buddy club cams from craigslist, and need help identifying whether theyre spec III's, or IV's. he said they were "stage 2", which is spec IV, but he looked like he didnt know what he was talking about...

i e-mailed buddyclub and they said theres a "A" stamped on the side but saw nothing.. no markings what so ever.

anyone got any measurements, pics, or whatever to help me ID them?

 

t=3+'S
a=4's

 

wheres it stamped on? i cant find anything..

i looked up a picture of their cams, and the lobe designs are identical.. anyone got any laying around with a dial so i can compare measurements or something?

thanks
