hey guys a few questions, im new to the newgen trucks, the my last trucks were 454ss's and tbi wasnt worth realy playing with, first off my truck is a 04 4.8 with the 5sp, 1 i want to know how you run no cats with out disturbing the pcm and 2 how much work would a t56 swap be, are the tailshafts the same and would the driveshaft need to be shortened, and what flywheel should i use? thanks
