And the LS7 Monte SS King still reigns SBE NA LS7 Champ...thanks CPR for the validation opportunity!!! CPR's 698RWHP vs 704RWHP on my buddy Steve Barker's Dynojet in WA State but look at the A/F upstairs, PIG RICH today....if I would of had Joe lean it out a bit to match the 704 A/F I would have EXCEEDED 704 lol, so there you have it after the car has sat for 4+ years moving from WA State to AZ!

I still need to tune low speed off idle for drivabilty, just never have yet.....it's fine at road speed though with no real tweaking.

Agreed but with the landscaping at the house "in work", pool construction, extended vacation, etc. unfortunately it will be a while. Not to mention that since NO ONE makes a C6Z header/exhaust system to my required specs guess who will have to make one....

This confirms that I want an LS7 square body wagon with a T56 for my DD (since a CTS-V M6 wagon is not attainable). Always loved your setup and I totally understand life getting in the way of cars!!
