LS3 Swap into a 1980 Wagoneer

[Mr. Church]

Looks great so far! Im collecting parts now for my LS swap. Looks like its the correct shop for it to be happening though! Bet that Jeep never thought it would be under a GTO

[ls3waggy]

Lol yeah, it has never been in a shop this nice with the exception of the dealership, guaranteed

Drool! Nice project.

Curious why the 2wd 4L80E though?

[Achilles]

He dose not have the TC adapter on it yet. He mentioned it in the caption above the photo.

Yep! Still acquiring some hardware to bolt everything up.

So someone is now making an adapter setup to utilize the 2wd output shaft?

The NP242 AMG was put behind the 4L80E trans in the humvees. So all it needs is the 4WD adapter that came factory on the 4L80E, nothing custom. It was just easier to find a 2WD 4L80 at the time.

I have a NP242 AMG and a 4l80e sitting in my garage from an H1 hummer.
My shaft appears much shorter than a standard 2wd 4l80e.

It is 3" long (stick out) from the rear of the 4l80e case.

Can provide you pics & measurements if you need 'em?

EDIT: It's for sale as well if interested?

So, what have you found that will not clear so far? Heater box? Brake booster? We will be doing some LS swaps soon so any and all info you can provide would be greatly appreciated!

Couple updates: Waiting on just a few more parts then its off to paint!

New CTS-V accessories fit like a glove. Looks like we can keep the battery in the stock location

We may need to change the tailshaft housing. I'm going to wait until the adapter comes in before we worry about that.

I'll update this week when its all together! Sorry for the late reply.

I'm not sure on the heater box since we aren't going to be using it (going to a vintage air setup) I can try and throw it back in there and snap a picture if you want. But other than that honestly nothing. The brake booster has plenty of clearance, I'm fairly certain this motor is physically smaller than the 360 which had a fair amount of room in there to begin with

We are waiting to mount the trans and transfer case to see if it clears the fuel tank (which supposedly isn't a problem on 80+ trucks), and if we used a different style accessory drive we would have had to relocate the battery. The oil pan (whatever style that this motor comes with) is pretty close to the diff, I may end up replacing it with a truck style one, but this is going to have a lift on it too, so I may end up leaving it.

Radiator and hydroboost are in! The radiator is awesome, as well as the fan shroud, Novak makes some amazing stuff! I would definitely recommend them if you're considering an LS swap into an SJ. (the hydroboost isn't mounted correctly in that picture BTW, I didn't realize it utilizes the old plate off of the stock booster)

Still have PLENTY of room with the motor mounts on the middle setting. In case we have to move everything forward for the 242 to clear the gas tank.

To answer this question the heater box is very close, similar to the old motor except this time it's in close proximity of the coil packs. It may fit but it's definitely going to be tight if you used the stock heater box.

That's exactly the info I was looking for! Thanks! Swap is looking good!
