Its a brand new cam never used. This is the same cam they have to use in the SCCA World Challenge C6 vettes, and Caddilac CTS V. PTV will have to be checked. 3.73 and lower would be my recomendation. There is somebody on this board that is actualy running this with an A4 
Sleep on it if you have to

Ive done some reading up on it, and ive always been curious about it, just not the 450 dollar price tag from GM. The GMPP LS6 heads that go with that cam are milled ~.055 so im not worried about it not fitting in my stock headed car. Yea, ill sleep on it (it seems like the only reason im sleeping on it is so i can say i didnt impulse buy it)
