~Duramax/Allison in a Jeep?~

Has anyone ever even considered this?
I may have access to a perfectly good twin turbo Duramax and six speed Allison with a t-case soon.
The Allison is pretty big. I don't think it would fit between the frame rails on a Wrangler, or would it?
The Duramax is a 6.3L, so is that the same size block as the Chevy 350 or there-about?
Dana 60's would have to be used for all that horsepower being delivered.
I have a friend that swapped the same power train into his H1 Humvee. It stops for nothing (except narrow passages )

Just putting this out here for discussion to see if it's worth doing.

I have a 1950 Willys Wagon I could maybe throw it into?

Betcha' wish your girlfriend was as dirty as my Jeep!

Hang on! This is gunna' be a thrill ride of geriatric proportion!

The deck height is WAY too high for a modern jeep and the Allison would take up almost all the space between the rails, the Willy's would only be worse.

I have a 1961 Chevy that could benefit from that.

I had a hard enough time shoehorning a Mopar big block into a 51 Willys pickup. I can't ever imagine a Duramax. It would be awesome though. Check out the build in my sig.

A cummins b3.3t BARELY fits due to the height. A full sized diesel V8 would be way too much motor.

Probably NOT a good idea. First, it isn't going to fit well, Second, excessice front end weight, and finally, all that torque will shred the frame and chassis.

Yep, thats alot more feasable, Id guess youd still have some reinforcing to do. Really if I were to do a diesel in anything it would be of the 2 wire hookup sort.

Well I hate to see that huge power plant go to waste.
Maybe I should buy an old Chevy van and make a mid engine rock crawler.
I have no idea what to do with the power plant if I can't use it in my Willys Wagon.
I'm sure the computer system is pretty complicated too.
Maybe just sell the power train and get a nice Cummins 3b for my YJ or the Willys.

Measure it. It MIGHT shoehorn in the Willy's if you arent afraid of some fabbing....

What ever happened with this Duramax/Jeep idea? I have both a CJ7 and drive a Duramax daily and I have pondered the same idea for a LONG time.

If you search for "Powerstroke Jeep" on Youtube you will find many videos of a CJ7 with a full Powerstroke drivetrain in it and that thing is BADA$$ man.

I'd love to hear if you went ahead with the project. I plan on getting another CJ7 and doing the Duramax swap myself. If a Powerstroke will fit then I would imagine a Duramax is possible as well.
