    Anyone build a rock crawler engine?

     



    I have a 1790 lb Track-T with the 2nd to last engine being built was the typical circle track (low buck) output of 386 hp @ 5900, 392 lb/ft @ 4400. I decided on a different route for the engine that I'm running now, 383 stroker with only 320 hp @ 4050 (not a typo, 4050) but 516 lb/ft @ 2800. The last time I was on the dyno, the technician asked if I had a rock crawler engine. What ARE the typical outputs of hp and torque at their peak rpms for competitive rock crawler engines?
