Help indentifying this cam
I recently got a cam from a friend of mine that he had pulled out of his LS1.Its supposed to be around a .595,but i was wanting to get exact specifications if at all possible by measuring.Dont mean to sound ignorant about this but im new to it.I read the cam guide,but none of my calculations are correct.Below are the markings on the end if it makes any sense.Thanks
