I have a 1994 chevy k1500 with a 350 tbi. I was wondering if any body has swaped the tbi motor for the 5.3 vortec? If you have i was wondering what i have to do to swap it? I know about the wiring. Will i need to put a newer 4l60e in it also? Also what will i have to do about fuel dilver? What should i do about exaust on my truck strait pipes or a good mufler?
