GM SUVs: Duramax with 4L85E?
The SUV poll makes me share this brain fart here. The big draw to the Excursion is the diesel. One of the problems with putting the Dmax in the GM SUV is everyone wants the Allison which doesn't fit so well.
But GM puts the Dmax in vans with the 4L8x transmission. I'm sure it's derated from the truck motor, and you don't get the Allison features, but would there be interest in that? I wonder how similar the 8.1L and Dmax engine mount setups are? I'd have to think it would be an easy swap...from a fabrication perspective. And the 85E with some mild upgrades could probably handle 500+lbs of torque no problem.
And then there's the newer 6spd trans; I wonder what they'd hold?
I'm torn between trying that swap, or finding a crew cab with quadrasteer and dropping the Dmax in one of those.
Thanks,
Michael

From all the understanding the trans tunnel isn’t the issue it’s a tapered body lift to accommodate the cooling stack the builders don’t use a body lift all the way back
