For comparison the stock LS1 cam specs :
01-02 F-body 197/207 .467/.479 116 LSA
The 02+ LS6 cam: 204/218 .551/.547 117 LSA
05-06 GTO 204/211 .525/.525 116 LSA
Heres something more amusing to consider, this is a stock LS7 Z06 engine with some high $ headers on it, not too much else, damned 427 is evil.
Weeeee, over 400 RWTQ from 3k-6300, yeah that will put an owie on the competition.
