I just pulled out my stock cam and laid it next to my Comp Cams one. Two differences I'm wondering about: the stock cam (top) has a groove in the 2nd journal from the front, and the Comp Cams one has something near the rearward journal. What are these things for? I'm guessing no need to worry but I am curious.

Bo, is the groove only for VVT, or is it for both VVT and AFM?

Our cars do not have VVT.
The GT only has the AFM Technology

Duh, we all know that the L76 does not have VVT. Written more clearly. Does that 2nd journal supply the oil for the AFM manifold?
