I’ve been living under a rock, and found Irate4x4 today.

I started this thread years ago on Pirate, it’s been sitting in pieces for a few years awaiting motivation.

I sold the old drivetrain, 304,TF727, Dana 20, those are hard boat anchors to find buyers for.

I pulled my LQ4, 4L80e from the donor. I pulled the 6.0l apart for rings, bearings, Summit 8720 cam, ported 706 heads. I’m finishing the porting this week and sending everything out for hot tank cleaning. The only other issue I found is that one mounting ear is broken off of the 4L80e, oh well, going to send it!

The rebuild includes swapping to 3link front, 79 Ford dana 60 front axle, 14 bolt out back. I sold the original dodge dana 60s a few years ago.

Yes, That’s my old Toyota, I tried to remove the image, I didn’t mean to upload it. I struggle with technology. I apologize.

The transfercase is Somewhat undecided. I have an Atlas 2 that needs a rebuild and input shaft. I have a manual shift NP263, and I have a customer with a Stack 3 speed for sale.

Here are a few old pics of the actual vehicle in question. This is on dodge dana 60s and 37s.

Made some progress. I got my engine back from the machine shop and started to assemble it. New wheels came in the mail too.

Making some slow progress. I got a couple of the 40” Nittos mounted.

Engine and trans are bolted back together. I verified I have the full splined output shaft in my 2wd 4l80e.

The swap headers point directly at the ears on the 4l80e, probably going to chop off the flanges and weld on some Vbands at a different angle.

Pulled my atlas out of storage. It’s a 23 spline unit, the story was the rear CV broke while being flat towed, it broke the NV3550 tail housing and it slid down the highway. I paid $300 for it, I believe it’s worth fixing.

The case is fine, a few bumps and bruises. The low shift rail has the threads broken off. The low shift fork is broken, otherwise looks ok.

I’m going to order the parts necessary to repair it, a 32 spline input, and some 1350 flanges or yokes in the next few weeks.

Seems weird that someone would manufacturer headers that point into the trans like that, what were they designed for? where are you located, pics suggest maybe midwest

Had some parts come in the mail from AA. I installed the 32 spline input shaft, measured and cut down the output shaft of the 4L80e, it has the “RV” 2wd output with long splines. The input bottoms out with roughly .187 gap between the mating surfaces.

Anyone else run into this with a factory 4x4 transfercase adapter. This one is the 15724745 - ADAPTER, from GM.

Am I stuck running an Advanced adapter 4l80e to Atlas adapter? This one is 2.5” thick.

Can you cut one or the other down? Or make a spacer from flat plate? Sounds like a piece of .25 plate would work...or 3/16 if you really like to keep tight tolerances.

I've considered buying a cheap clocking ring and just using it as a spacer. Another possible solution is to chuck the input up in a lathe and cut the splines back 3/16. Either is a fine solution, I guess more curious what others have done. This is a very popular combination, but there's very little info online about bolting it all together. I found the part number online for the adapter in another forum but didn't see anything about this issue.
