Make sure you calculate the weight you'd put on the front end with that engine. It will be a ton.........

That 12valve has a weight of close to 1300# give or take, with all the accessories on it. The frame,and driveline won't handle that weight, or the torque. And I'd bet it's too long (I6) to fit under the hood without severly chopping the front of the tub out. The reason they went to the longer nose in '71 (?) is to put the Jeep I6 engine in. And the Cummins is quite a bit bigger yet. Just my opinion, either do a 4BT, or a v8 swap. Easier, and less expensive when you start to factor the driveline/frame requirements.

my .02, if you are looking for diesel find a smaller 4 cylinder out of an Isuzu. They are great motors in my experience. Had one in an old Chevy LUV and it was bomb-proof and had no problem towing a couple thousand pounds of garbage on a single axle trailer when i loaned it to a friend who was rehabbing his house (the brakes weren't really up to it though. They were also used in troopers i believe which would make finding a trans/case configuration for the jeep easier. And if you need more power throw a turbo on it.

Also I agree with hot stuff, you'll be pulling a nose wheely ever time you hit the front brake with that much weight forward and it will take some really stiff springs to compensate making the ride even harsher.
