That's 11 lb-ft improvement over the Corvette's version of the LS7 (rate 470)and, packaged in a 600+ pound heavier car, I'll thank Powertrain for finding that. That is very important for this car and it's intended usage, and far more significant than a few more horses...

I mentioned that in the Official Release thread. Would the tri y headers get the extra 11 lb*ft?
