FWIW, Lightnings make peak tq around 3k to 3200k. It's hard for a lot of us to get a true torque # as well. Check out my sig (tq #'s at the rpm specified and explanation)!!!

My buddy has shown me more research on Vettes than I care to see, and believe me, they're all putting around that much HP/TQ to the wheels when they're stock, or close it, "just to let everyone know". The run on his Vette was started low, MUCH lower than with our trucks. The graph continued to climb. You couldn't possibly start too high in a Vette, the torque peak is up there higher than you'd ever start, it's not a torquey vehicle.
Here's a blurb from a dyno from Magnaflow:
http://www.magnaflow.com/05news/05corvette.htm
Of particular interest was the MagnaFlow vs. OEM Shootout. A baseline dyno run was pulled on a bone stock C5; the run resulted in 298.6 horsepower and 306.1 ft lbs of torque being produced. Forty-five minutes later the MagnaFlow over axel system was installed and ready for the comparison run. The results were in, the 'vette produced 309.5 horsepower and 325.5 ft lbs of torque, for a gain of 10.9 horsepower and 19.4 ft lbs of torque.
So yes, this one put down 20 more TQ and a few more HP but it was also WAY hot today which will definitely suck some HP/TQ from any vehicle. Don't be fooled, Vettes are not torquey vehicles.
There was also a dyno run on their wall of dyno's of a Z06 with headwork, intake, exhaust, and something else. It was around 375HP/360some TQ. I would have expected more, but maybe there's not as much to gain in the Z06 motor.
Just wanted to clarify things a bit, this isn't a Vette bashing post (although i smoked him BAD when we raced!!!!!)
