4wd is 50/50 split power to front and rear and the awd has i think 62% to the rear and 38 % to the front.

however i think with over 600-700 hp on awd is where problems start , but we will see if one can handle over 1000awhp through an 80e for any period of time soon enough.

Yep! Sho Nuff!

I chose to keep the auto-trac behind the 80e,added the 6 pinion planetary's from the 2500 hd T/case to mine, and a 14 bolt w/tru-trac. The 50/50 split should hold off the pad and the push button to release too drop into 2wd after 1-2 shift, in theory would be getting best of both worlds.

And I only want 700+ @ the wheels.

AWD is much smoother. Autotrac driving on the street is a bit harsh.

True...and 4wd doesn't work out very well on dry pavement, the front end has a tendency to bind around turns.

Mine has the AWD/4WD (hi&lo)/2WD selector. I use the AWD more than I ever imagined...especially with all the torque on wet streets it makes a huge diff.

That is correct. I have disconnected mine and no lights on the dash.
