RE: Could this be competitive?
That engine should move that truck fine. The 053 is a torque pipe if I'm not mistaken, which is really gonna make an already torquey motor more torquey. If the 007 is a high speed pipe, I'd go with that. I've raced with guys that have run the Mach and it does well against the race motors, but longevity may be an issue. Their motors were just about shot at the end of the season.
