Lid, flowmaster cat back, and HPP3 mine made 317hp. With 3psi of boost and a cut out, I made 375hp. Now doing headers, getting 5psi, no cats, no cutout, new valve springs, redone rockers, magnaflow catback, I really would like 450, but I will just be happpy on a stock long block for 425....

I think kraest is pulling ya chain there....
All LS1's make the same hp whether in an F-body or Vette. GM was kind to us and underated the F-body's hp.
Stock LS1's produce 340-345hp/350tq at the crank and between 290-310hp at the wheels.
In both crank and actual power at the wheels the higher numbers go to 01-02 M6 cars while the lower numbers tend to be 98-99 automatics. We of course are talking STOCK!
