Hey guys my name is Johnny and Im new to this forum. I have an 08' Colorado with a 4banger that only had 70,000 miles and locked up on me. Well, yes as you all know Im wanting to drop a 5.3 in it seeming it is already paid for and I can do what I want with it. My question is, is there somebody out there that has already done this and if so could you supply a complete list of what is needed to make this happen? From motor, wiring, to drivetrain. Any and all help would be greatly appreciated.
