Something that you might consider is using a 6.0 out of a 2500 truck, vice the SS. You can do some very light work to that motor to get ridiculous power output, like the SS and then the computer would talk to the engine easily, even with 4WD. Also, I did some research, the 2500 pick ups don't use hubs, like a Ford. It uses a gas operated piston in the front diff. When you pull the selector to 4WD, a 12V signal is sent to the front diff. That signal heats up the gas in the piston, which then expands, like gases that are heated do, and the piston extends, locking the front diff. Instead of using an electronic signal to lock individual hubs. Sounds like this might need a Solid front axle.

One thing I am considering trying to do someday (when mine is paid off, which is a few years away) is taking the TB body off and putting on a K5 Blazer frame, or short box Silverado frame just for fun. Something different.

I've gonna side with the majority of people here. I've destroyed a tranny and rear end(separate occasions) on my 4.2L with only basic mods. The tranny isn't that great to begin with in strength or in performance.

Manual transfer case

Hey guys after talking to a few of the guys on the website we decided that I should bypass all the electronics and just go with a manual transfer case. We decided the 2500 will work but i'm trying to find one!!! I've called dozens of junk yards but no luck. I'm going to cut a hole in my floor and have the lever come through the floor board.

The lever through the floor should be relatively easy. Just make sure you have everything positioned properly before you start cutting the floor. Just a thought. Are you using an SS 6.0 or a 2500 Silverado 6.0?? Just not sure about the computers and trannies, and transfer cases working together.

Just FYI, didnt see your last post but the 6.0L out of the trucks uses a different PCM than we do. Still going to have electrical issues. The PCM used in the 02-05 I6s is UNIQUE, as in NO other GM car/truck/SUV has or will ever use it again. The 06-07 P12 is shared with the Colorado/Canyon/GMT355 trucks and Cobalt SS S/C /Saturn Ion Red Line. 08-09 E67/T42s are shared with a LOT of GM cars/trucks/etc.

what's the deal with the pcm's? do they interact with the bcm? if not, i don't see why you couldn't swap a 6.0 pcm/harness out of a 2500 onto a SS drivetrain and reprogram the 2500 pcm's tables...

Yea, I thought they were different Erik. Wasn't sure what the difference was, but figured there were difference, being that the HP and TQ numbers differ so much with the different vehicles. Like I said, not sure about the computers, and how they'll interact with the different components. Thanks for the info Erik!
