The Duramax's really don't impress me towing, so my money is on the 6.0L! As far as handling the weight, the suspension and handling of the Ford is going to run circles around that glorified half-ton Cheby...

I would think they should tow about the same. The LBZ is one of the more stout Duramax motors. The Duramax will probably get better mileage towing, but I've seen Superduty's pull AMAZING things

MILEAGE WISE, you are 100% correct, but if we could shed 1000#'s or more of a Super Duty it would improve as well.

I frequently service an 05 that definitely feels much smoother than my truck but power wise it doesn't seem to have any benefit. don't care for the shift feel either

My last truck was a 2005 LLY DMax and don't get me wrong, I loved the truck. BUT towing was not fun. Everything just seemed sub-par.....shifting while towing, handling, etc. My 6.0 in my sig tows better than the old DMax even though I have 8" of lift.
ALSO, some people will argue to the death on this (DMax owners) but I believe the Ford tranny is more robust than the Allison. Might just be my experience with it though.

My dad has an 06 LBZ, I have an 04 6.0. I think the Dirtymax motor is far superior in the power dept. The chevy feels like it has more guts down low where it seems like my ford revs higher and doesnt really move out. Now both trucks tuned, the chevy didnt seem to gain much but my ford really woke up. I like everything else about my ford better though.

I can see where you would say this, but what about highway speeds hitting grades? Personally, in highway speed situations while towing the Dirtymax's really seem more like a DuraTURD to me.....

There's no argument that the Torqshift is a stronger tranny. A Durajunk will spit the Allison out with just a 90-100hp canned tuner. You see people all day long running 140rwhp tunes on a Torqshift and they take it!!
