Seriously, if you are looking for 350ft/lbs of torque, why are you looking at diesels? Those are stock 6.2 non-turbo numbers. The 3 liter diesel in my BMW makes well over 400. You are really looking at 4bt numbers, and you can back it with a 700R4, 4L60E/4L80E (if you want to deal with electronics), or any 5 speed manual.

6.0 gasser will easily surpass those HP/TQ numbers and be a fairly easy drivetrain swap. From having done a diesel swap myself, there are A LOT of little things that come with changing from gas to diesel. As much of a fan as I am of diesels, I agree with Hatzie on this one that you should take a serious look at the 6.0 gasser.

Towing 10K lbs on a 1/2 Burb chassis? You might want to rethink that. That 1/2 ton running gear also won't live long behind anything larger than a 4bt. A Dmax/6bt/DT360 will blow the ring and pinion out of that rear end the first time you nail the throttle. I had to upgrade my Jeep to a 14bolt for that reason.
