I have a used F13 -112 LSA cam with about 3000 miles on it. I want to trade it for a ZO6 cam out of a LS6. It is currently in my A4 Z28. I love the cam, sounds awesome, runs great, but am moving to California and it won't pass smog there. I recently drove over 1000 miles, and averaged 25 mpg with the cam. I still have the card and box it cam with. With installing the cam, I gained .5 sec in the quarter mile and about 29 hp. I can remove the cam and mail it ASAP. i need to do this by the end of July.

Here are the stats of the cam.
FMS-F13-112 FMS Custom Grind Camshaft - 230"/232" .595"/.585" 112LSA - aggressive profile with a 2500-6800 RPM range, rough idle
