Need ideas

[Fugzilla]

Ah, I see, your initial post made it sound like you were wanting to go 4x4 or AWD from a 2wd...
The mid-2000 Trail Blazers and Envoy Denali's with the V8's were part time 4x4 with 2wd as the normal mode. Their T-case should bolt up to your LM7. You will need the computer and all of the wiring as well. I don't know if the 4x4 mode ties into the anti-lock brake system or not or what changes would need to be made to the GMT360 ECU to work in the truck...

And there won’t be any binding issues? also I have a 4auto selection I’m looking to do full AWD as an option to the 4x4 hi,low,auto and 2 hi .... if that makes sense also I’m not afraid of a challenge
