Can't find any information on the 454 ever being installed in a 2500. Do a Google search and see what you find. GM did put a 454 in the 2500. I believe that the horsepower rating is about 290. Unfortunately i don't know about torque. i own a 98 k2500 with a 454,The Vortec 454 stock puts out 290HP 410TQ,
