want to do that in my 2011 Colorado so i found a 2011 6L LS complet with wiring and ECU....but i think i'm gonna use a OEM V8 5.3L Colorado engine harness and ECU from a local GM part dealer only cost $600 each ;)
Your truck turned out great. Nice work and thanks for sharing your experience. Going to be doing a swap before the end of the year. Still in gathering stage but getting close. Do you have any contact info for the guy who helped out with the wiring hurdles? Thats the area I'm most apprehensive about...
Thanks man! Out of respect for his privacy I won't give his personal info out. My advice is to pm him online @04colyzq8. That's his handle on all the 355 truck forums. If he's free to do work he should reply.
Stock fuel pump, used a corvette filter with a built in pressure regulator to eliminate the return line and just plumb one fuel feed to the engine bay.
I’m getting ready to do this swap on my 04 Colorado, as far as the transmission, automatic 4l60e what needs to be changed besides the bell housing to mate to the 5.3? I’ve seen some forums talking about the input shaft, does the whole input shaft have to be removed and replaced?
