I'm not pulling the cam, lol, that thing was a b**ch to get in and it aint comin out until a rebuild! We spec'd it before it went in, it was definatley an 02, we even checked the stamping on the end, 02+ LS6 part #. It was a ebay purchase from a guy with an 04 vette, so i had to make sure i got the real deal. I will say however, if I am losing anything from too short of pushrods i cant tell, i will find out when the rods get changed. However when I checked part #'s the rods, rocker arms, and one of the valves all matched between the 5.3 and LS6. I'm definatley not saying I am wrong or right, just going by experience.
