Hi, I reccently bought a set of used Cosworth M2 cams from a member on here. They showed up today, and the exhaust cam is clearly marked. The intake cam however appears to be a stock cam, and I just wanted someone to help me check if it is a stock cam, or really is a Cosworth. It is hollow like stock (which I've never seen a hollow cosworth) and has no clear manufacturer markings, just a few serial numbers and such. Also the texture is much rougher then the other. I'm including a few pictures. Thank you in advance.

 

Nobody?
