how to tell what ZO6 LS6 cam it is 2001 2002? or what???
so i buy a used LS6 cam, havent installed it yet at all it looks very VERY nice and is in awesome shape for being used. Looks kinda new actually but i wanted to know how i can tell if its an LS6 cam(and if its a 2001 LS6 or 2002 LS6, and yes there IS a difference with lift and LSA if i remember correctly!) It still has all serial #'s all that crap engraved on it so im guessing someone can tell me if they know anything about the numbers. I have a STOCK LS1 cam out of my 1999 LS1 laying around and tried measuring the lobes with a millimeter measuring thing and they came out very similar if anything the "LS6 cam" lobes measured to be smaller than my stock LS1 lol.... WTF?? someone please shed some light i dont feel like going to the dealer right now its kinda far THANKS!!!!!!

If not its off to the dam dealership and pray some idiot in the parts/tech department can find anything to do with those lil serial numbers on the cam

sweet thanks for the info guys i will double check the measurements and make sure at the dealer that what i have is what i originally though i had. Imma also look up the part #('s) for my stock 1999 LS1 cam as well to see if matches up and 2 see if i actually do have the 02 LS6. thanks again latR

The proper way to find the lift of a cam using calipers is: Measure the Largest point of the Lobe (Lobe Height), Subtract the Smallest point of the Lobe (Base Circle), Multiply that value (Cam Lift) by the Rocker Ratio (LS1 = 1.7). This gives you Valve Lift.
Example: 1.0568" (Lobe Height) - .7480" (Base Cricle) = .3088" (Cam Lift) X 1.7 (ratio) = .525" (Valve Lift)
Example: 1.0568" (Lobe Height) - .7480" (Base Cricle) = .3088" (Cam Lift) X 1.7 (ratio) = .525" (Valve Lift)
