In July of 2022 we ordered a bunch of interior stuff. Carpet, seat cover, door panels, etc... This stuff has been stacked in a corner of the garage and a couple of weeks ago, we decided to get going on this. Deconstruct:

2023 Activity:

Did a bunch of miles for project Annie since then as well:

I did this in November of 2021 after I got the front height "right". It tracks well and the tires look ok as far as wear goes. In the 2 years I've had it on the road I've logged about 6,300 miles. After we got the front end squared away we added the receiver hitch to the back and started doing truck stuff:

I have been unsuccessful in getting it to the frame shop and have been wondering lately if I got it aligned at all. Based on the following picture, the answer is kind of:

Its been 2 years since the last update. Shortly after the last update I swapped out the front springs and instantly had an uneven condition left to right by a noticeable amount. I played around with spacers and finally ended up about 1.5" up. iirc - the springs are supposed to be a matched set but I have a spacer in one side to get it level.

need new project for 'unloved' motor you're welcome

I had actually though of that. The Caddy is next up though and I don't have room for everything I have. Maybe I can trade the 5.3 for lumber to build more garage!

My plan when I bought the junk yard motor was to run it for a while then swap it out for the rebuilt one at a later date - selling the JY motor to recoup some $. If I was on track with that plan the truck would have the new motor in it and the one in the truck would already be sold. As it is now, the motor in the truck seems to be running very well. It has 60lbs of oil pressure and probably enough HP & torque for what I want it to do. This has me wondering what I should do with the rebuilt mill after assembly. We've tossed around the idea of using it in the Caddy but we are not sure that is the right choice. We've got time to make that decision though as the soonest we would start blowing the Caddy apart is next year in July (after the 50's weekend). The Nova is also another option, but that runs so well and is so generally "right" I really don't want to mess with it that way.

Stopped at the frame shop yesterday and he is confident it can be fixed. Unfortunately, he is crazy busy and doesn't know when he can get to it. I am hoping for sometime before spring. My new front springs showed up a couple of days ago so that is this weekends project. Stay tuned for revised ride height pictures.

I really like this project, however it has convinced me NOT to go LS in mine just yet.

I'll save my LS virginity for phase 2
