Ok Im looking to buy a zz4 cam off brodycamaro and he got it off ebay and isnt for sure its a zz4 (I got screwed on ebay already so im paranoid) anyways he said these numbers were on the back of the cam.

307 OOR (could be zeros im not sure)
071 FM35

could someone check those out and see what they are? are those even parts numbers?

Looks like #'s that we have found on other zz3-4 cams.
Do a search for #'s stamped on the cam end or something similar.

 

Ok I did a search and looked through about 100 posts and didn't find the post/reply you were reffering to. Maybe you could narrow it down some?
