I just scored a deal on two D44 front axles and NP203 for 130 bucks. Now I just need to grab a rear axle and some springs.

Today I will be spending my time drawing out the water pump bracket.

I lucked out with the fitment of mine. Fits so nicely. Your 3.4 is 3" wider and 6" longer than my 3.3. And 70lbs heavier which isn't a big deal. In the pic of it on the trailer the tires look so small. :/ Ive got the 6AT installed. Just waiting for the guy to deliver the SM465/NP205 combo to my house. Since my Dakota Quad Cab truck blew its 4.7L it has left me without a truck. I'm curious to learn if the 6AT 3.4 and the B3.3 share the same crank pulley specs. The 6AT uses a grooved pulley and Id like to convert over to a serpentine pulley system. It uses a center mounted crank bolt rather than the four tiny bolts on the 4BT and 6BT. ATI said they would make me one for the same cost as that of the 6BT. I have seen new B3.3 crank pulleys at a quarter of the cost of an ATI.

Monday I pick up my most recent SM465/NP205 purchase and install in into the MJ. Then fab up the cross member and bell housing motor mount brackets. After that I will need to put together a rear driveshaft so I can test drive the truck and work out any bugs. Before doing that I fist need to finish the engine install and the hydroboost brakes as well as a few other things. But the engine is finally in.

The Engine is IN!!!!! Ok so everything is still being fab'd but the two motor mounts are welded up and bolted into the MJ. It all still looks like chopped arse and I am still in the process of cleaning things up. I think it turned out pretty good. The engine fits under the hood rather well with a good amount of room left. I put the hood on just long enough to see what it looked like and how much room I have left. Here is what it looks like with the hood on. And a poor photo of how it looks underneath the hood. Here is a shot with the engine sitting on both motor mounts with the drivers 1st and the passengers side 2nd. They still look ruff but after I clean them up it should all not be so much of an eye sore. You can see where I drilled holes into the tops of the mounts. Those are welded on but I will be putting a bolt, washers, and nuts through them both to give better strength. Here we have the GMC hydroboost I will be installing. Test fit. Next I will need to buy another SM465 with NP205 mated to it as I am having issues finding the correct NP205 (six bolt with 32spline) in my area. I did find one but I'm not paying 450 bucks for a used oily t-case when there are plenty other NP205's for a 1/4 of that price.

I now have the passengers side motor brackets and mount fab'd up but won't finish it until I have the transmission support bracket fab'd so I can properly align the engine and transmission. It's all coming along nicely.

No.... lol.... its welded to another bracket that bolts into the bolts motor mount locations.

Here is my drivers side test engine bracket and mount. I used motor mounts from an early model CJ as they were only 5 bucks each. I still have some more work to do on it but for now this is what it looks like. I am going to work on the passengers side today and then make any needed adjustments. We will see it they can endure a little road time after everything is installed. I still need to make the transmission cross member and add mounts to both sides of the bell housing.

Update:: Today I was able to do some work on the project. I pulled the engine mounts off the engine as well as a few other things getting in the way. I bolted the SM465 with the GM1 bell housing to the engine so I could stage everything and take some measurements. Here is what she looks like in the truck. And here is it in the trucks cabin with the transmission shifter in place. The crankshaft pulley/harmonic balancer sits about ten inches from the radiator mounts from beam as noted here. Tomorrow I hope to design and weld up the new motor mounts and the transmission support bracket. If I have room I might also incorporate another support bracket at the bottom of the bell housing.

Awesome to see the project coming along. I'm having some issues of my own on my Cummins project.

I took some photo's but they would not load into photo bucket. So I will try and explain without photo's. Today I cut out the firewall as needed. I'm still having some clearance issues with the SM465. It fits in the tunnel but on the passengers side is the location of the fork and slave cylinder for the clutch. There is not enough room to use the current setup. In other words I am not able to use the fork and slave cylinder. The transmission still needs to be lifted another 5 inches and that places the fork and slave cylinder in an area that would need to be widened another 7 t0 8 inches leaving not much room for the passengers feet. Unless someone has another way of doing it and has photo's to show what things look like. I have thought about trying to adapt or convert the SM465 to an internal slave cylinder. I know there are some kits but I don't feel like paying more money for something I know can be done in my own garage. I am open for idea's. Anyone??

The passengers side looks ruff but its just the way the photo was taken. Its just some basic surface rust. Sand it all down and paint over it with some POR15.

Here are the drivers side floors. That is mostly surface rust from what I can tell after testing the thickness and strength of the metal. There is a small bit of cancer under the gas pedal.

So Ive pulled everything out for the most part. Here is the firewall and some of the flooring.

Ive a herniated disc in my lower back thats keeping me from the project for now. Its driving my nuts not being able to get out and do something. My wife is watching me like a hawk. Hope to be back out in a few days and hope no more then a week.

Status?

So today I cut and removed the remainder of the exhaust pipe. Then pulled the Cummins out of the engine bay and set it aside. I drove out to me dads to get some of my tools and transmission jack that was left out at his place. So the truck is up on jacks stands and getting fitted with the SM465. Here is what is looks like as of today. This is the transmission with GM bell housings as it sits now. As you can see I was not able to push the transmission up into the tunnel due to it being to narrow. I will need to remove some of the tunnel so I can move the SM465 up six inches so that it fits properly for the Cummins 6AT. This is the inside of the truck... you can see how the transmission is lining up. And a shot to show how low the SM465 is sitting. The transfercase will be moved back about 12-14 inches.

Today I removed the dash.

Today I pulled the carpet, interior, most of the dash, seat belt, and such from the drivers side. I also looked at how much of the flooring was rusted out. Its not to bad on the rear half of the drivers side. Just some rust under the foot pedals and a hole punched through the flooring from the guy hitting something. I will remove what cancer is needed and replace with some sheet metal as its not a very big spot from what I can tell after testing the metal. Tomorrow I want to pull the passengers door, the rest of the interior/dash, and heating system. Then mark it where I want to cut the firewall and tunnel. I would like to set the engine back a few inches to help bring the center of gravity closer into the middle of the truck. The Cummins/SM465/NP205 combo isn't going to be lite. Push the truck into the driver way and hot soapy water time under the hood and inside the cab so I have clean surfaces to work with. I do have a few Q's that I thought I might pass by..... Using the passengers side drop t-case what axles would fit best under the MJ without sticking out to much? I do have a set of land cruiser axles Ive thought about using but then I would need to use the land cruiser t-case. They have 4.10's and disc brakes.

Today I got around to removing the drivers door and noticed the hinges have come unweld at the body. Guess I will be welding those and resealing them properly. I also removed the bench seat from the truck. Tomorrow if time allows from other projects I intend to remove as much of the remaining interior as possible. Then mark where I will be cutting the firewall and floor hump to accommodate the engine and SM465.

Have any pics of the install?

So its been a while and Ive finally come to the point where I can work on my MJ. I placed the Cummins 6AT into the engine bay just to get an idea of the weight and size of the engine in the bay and what mods will need done in order for the engine to fit properly. Here is what it looks like when sitting in the engine bay. I have decided to use the SM465 I have and currently seeking an NP205 t-case. I will be swapping out the front and rear axles for something stronger and going to a passengers side front pumpkin. The Cummins exhaust will be increased to a three inch straight pipe with no muffler. It is a turbo so the turbo acts as a muffler anyway. I also will be using a larger turbo, tuning the injection pump and using a better nozzle for the diesel injectors. Converting the engine to a front mounted intercooler. Other mods will include the conversion to an electric water pump, electric hydraulic pump for power steering, Hydroboost brakes, A/C, and HO Alternator. Dual fuel tanks for longer distance trips. Front Leaf spring conversion.

I haven't been under the truck yet but I think it just might be the CPS.

Well I made it home with a tow. But the issue still remains and I hope it is not something to serious. I see there is some confusion so I will try and explain. That connector with the wires hanging from it is whats left. You can see the black plastic is the female side of the connector. The male side is no longer there but those two wires have been plugged into the female connector. The male side has the red and white wires. The male side was pulled out of from where ever it is wired and left me with a two foot loom with two wires sticking out.

The plug that has the male end on it was ripped from where ever it was wired into.
