After not being home for the pass 18 months and racking up about 67k in that time my old powerstroke needs some help. I have thought of a 12v conversion but am considering other options what do i need to get around 550+hp and over 1100 ftlbs of torques out of a 7.3l ?? I am getting ready to pull the motor for a rebuild and also rebuild the auto trans. the truck has been good to me and is very clean and straight. I have done some research and have thought of a couple of differant option but i fiqured i ask and see what reaponse i get thanks, Jr
