the truck setup is 3.55's 33" tires, stock lift, no head porting or polish, ats manifolds, stock intercooler, 370's, FC dv's, modified AFC, no plate, 4k springs, and 60lb. valve springs. nothing special. im sure it is cabable of 550-600hp with the right amount of fuel, yes it's going to be hot on the top end, but i was after better spoolup, and all around better driving boost. it seems there are more than a handful of 12&24v trucks out there with 62 chargers making over 500hp. guys if you have more technical questions, ill try and answer to best of my ability, chris was more than helpful with answering all of my questions. he is super busy, but will get back to you in a reasonable amount of time. so don't hesitate to give him a call!
