Green Yj 6.0 swap

usethis · Sep 21, 2016

I have had this yj since 2008 and it was bone stock and pristine with the 4.0 and tf999 auto, sat radio and ac. I wanted it to be super reliable and comfortable compared to my former rigs. So I slapped some tons under it with detroits and 538's and atlas 2 and did a soa with rubicon express springs, setup up hi steer and rocked it for 5 years with 37s very comfortably with no breakage. It worked good but back then 37s were not considered daily driver tires.

In 2013 I decided to step it up and contacted an old buddy in Dothan who was starting a new shop. Motobilt. Folks on here know Dan does killer work and his team transformed my yj's suspension into this century and we used really good parts. They built crazy trusses, backhalved, custom fuel cell etc.etc.etc.

The rig works amazing and does great for general trail riding and tech rock crawling but it needs mo power.

About 2 months ago i picked up an lq4 and a turbo 400

Re:

I cut off all the factory stuff and cleaned up the frame for the new parts

New mounts fit tight and right

First test fit with the v8, looking pretty good and getting exciting

I was was relieved to see the link bar clearance to the pan. Exhaust is going to be a pita.

Re:

Put new flexplate on the lq4 to run the th400. Also an 1.25 adapter from advance for the th400 to work with my atlas 2. Also have a new 32 spline input from advance to install in the atlas

Re:

Quick check on the Sanderson Headers. Tight but doable and the engine is NOT plumb in this shot, just a mock fit to see how life was going to be the next few weeks.

Re:

Swapped out the input shaft last night in the atlas to mate to the th400. Going from jeep 23 spline to gm 32 spline

Looking good. Its coming along pretty fast.
Stupid question, but when you welded the engine mounts in, did you test fit the engine first?

Re:

@mihfield2005 yes sir will do something after up and running. The oil pan between the upper 4 link and cookie sheet tranny pan are exposed parts.
