At post 110 I changed my mind and decided I would build a buggy instead of the Wag. The Wag continues to wait for it's next build.

At post 187 I ordered up a GoatBuilt JHF chassis to hopefully speed this up. (edit: nope)

==================

I bought my Wagoneer in 1997. It was my first 4x4 and I bought it so that me and my friends could go camping and have room for our gear since we all drove econoboxes. That fall I ended up moving to Germany for 18 months and it went into storage.

When I got back I rebuilt the AMC 360 with the help of a friend, and we did enough maintenance on the rest to get it on the road. Over the next few years it got a 4" lift and went from 31s and then 35s when I put a 3" body lift. We did some wheeling with it and eventually I put it on 33 Stampers from my old Wrangler.

In around 2005 it was parked due to lack of time and using any spare time on my Wrangler. A few years later we stole the drive train for the TREC Wagoneer, and it has sat since.

Over the summer I got out of racing, bought a RZR and drug this back in the shop. I'm thinking I want to get it back on the road and trails.

Wow, that turned out great. I'm feeling more optimistic that painting it won't be a waste of time.

My short term plan is to have the drivetrain "ready to run" when it goes in. I know at some point I have to strip down the chassis for paint, but if I decide I want to build it out before doing that, I don't want to have to pull it apart just to do something that takes 5 minutes now. I know I'll forget something and pimp myself, but that's life.

Over the next few days I'm hoping to paint the iron block, pull the rear cover and replace the oil pressure barbell, rear main seal, and rear cover gasket. I need to pull the oil pan and put on a fresh gasket and seal the oil pan. I'll wait to do the front seal until I do a cam swap. I need to verify the flex plate matches my torque converter, too.

@Tom rebuilt my TH400 a few years back when I was optimistic about my finish date. It's been bagged in a corner waiting on me. From memory, I need to reinstall the shifter rooster comb, plug speedo hole, and swap the stock pan on instead of the chrome leaker, and trim the output shaft for the Atlas adapter combo. I guess when I unbag it we will see if I'm forgetting anything.

I think the Atlas is good to go besides gooping it up and bolting it to the trans.

I pulled the motor out of the donor, so I ripped it up and down the road a handful of times before removing it. I have the drivetrain mounts all ready to go, so not sure I want to temp wire & plumb it out of the vehicle. Next time it runs, I'm hoping to have all the support systems there. Hopefully that's well before August.

Ahem - it better be!

I spun the motor over and threw on the stock pan for cleaning. I unloaded one can of $1 store oven cleaner on it and let her eat. Watched a little 4400 power hour and then rinsed it off using a steam cleaner.
I’m going to let it dry overnight, and hopefully mask and paint tomorrow. Not sure if I want to hit the front cover or leave natural.
