This is a 383/396 that put down 423 and that is the "nastiest LT1 on their rollers"?

, power started falling off at about 6000. Torque was over 400 from 2900 all the way till 5400. it was also very HOT inside the shop ( i know dyno corrects this but it isn't 100% accurate) so there is more to be had out of it. Very happy with the results and the guys at Cartek were stunned that an old LT1 can put that down, according to them it was the nastiest LT1 ever on their rollers ( n/a). Now for 42lb injectors, the tune to go with them, and then a little giggle gas.

Or see this one...

When a guy doesn't have everything worked out and he still makes 423rwhp @ 5400! there is a ton more in it when it peaks at 6200-6500rpm. That will really wake up Cartek.
