Need ideas

Okay, I understand. My '94 Astro has AWD and my '08 Envoy is 4x4 or 2wd. I see no difference driving either one of them on dry pavement other then the Astro (LT1 350) won't spin a tire from a dead stop. The Envoy has a 5.3 and it will spin the back tires in 2wd mode and in 4x4 it won't... The two transfer cases and drive mechanisms are entirely different, I don't see how they can be intermingled to do what you are wanting to do...
I think the Astro transfer case is an NP136? I know guys are swapping in S10 NP233 cases to get the 4x4 locking 4 Hi and locking 4 Lo. I don't know if that case is AWD or simply 4x4...
Good luck with your project.

Yea fasterproms on YouTube has an awd s10 project kinda how I desired I wanted to go awd .... as far as the burnouts on awd you need a lockout for the tif to put all power to main drive wheels if you watch keenblocks hoonacorn makeing the only way he could do a burnout at a dead stop was if he had it chained
