I want to purchase a 2002 LS6 cam I found on the net. The gentleman selling it has sent me pictures.
Are there any physical markings or any way of proving this cam is out of a 2002 LS6? Any measurements on a particular lobe length?
There are some numbers stamped on it that read like this:
-----------------------------------------------------------------------
(These sets of numbers are stamped on the end of the cam)

29406r
1251

7552
287
--------------------------------------------------------------
1346a
27206 (This set of numbers are stamped on the body of the cam)
--------------------------------------------------------------------
As far as I can tell none designate a (2002 ZO6) LS6 cam part number, which is, 12565308.
BTW, 98-00 cam part number is 12560965 and 01-02 cam part number is 12561721

Hopefully someone has a LS6 cam on their bench and could possiblely verify those stamped numbers, or could possibly 'mike' a lobe or give some other type of measurment that I would only find on a LS6 cam.

Thanks in advance for the help.
