My stroked big block is actually up in the 680 ft lbs area. That was on an engine dyno.
I think the 408 is artificially high too. The graph they gave me shows three lines with one indicating the torque at 495 ft lbs at just under 3900 rpm. The horse power peak is up around 4600 rpm. The line that indicates the 525 ft lbs sweeps in from the left side of the chart. They didn't indicate what color represents what. I was there to verify my A/F ratios, not get numbers.
I tried to run it at the closest track, which is about 3 hours away. I had just broken the second gear apply band mounting post, so I couldn't get a decent time.
I've since had the transmission repaired and freshened, and will make another attempt in the spring. I expect the car should be somewhere in the 11's.
