Ok heres the deal I have a 2008 Silverado WT that is the base-ist model you can get. I want to swap in the 4.8 i got for free just no wiring harness on it just sensors, intake, injectors, coils, and everything from the heads to the oilpan is complete. I cant find any information on this swap in the thread is there anyone here that can help me figure out what I'm going to need to get this done.
