    I had seen a couple mentions on LS sites about doing this upgrade. Seems like a reasonable upgrade and not breaking the bank. Thanks for the link!

    I was bouncing back and forth on pulling the mains or sending it. Today I committed to pulling them. Since I want it hot tanked and checked etc the crankshaft has to come out. The main caps weren’t as bad removing them as I expected either. And to my surprise main #1 doesn’t look too bad, mind...

    Good to know, however I am not military. I’m mainly doing this teardown/rebuild for the experience.

    Pulled all the pistons out. Figured dirt got down into the block when taking everything apart might as well disassemble and send it off to be tanked and cleaned. Inspected the rod bearings and I’m not an expert but they don’t seem that bad. Camshaft is out and shows signs of wear. Reminder...

    Did some engine tear down today… Brought it to my garage instead of being out at the shop. Pulled the intake off and got to work pulling the heads. I’m not used to aluminum heads! Those suckers are light! Cylinder walls don’t look terrible and there isn’t any noticeable damage...

    I might just leave it as is and get a standalone harness and call it good. Of course new gaskets would be a must since it’s got some leaking going on. Well scratch that I noticed 3 exhaust manifold bolts were broken off in the heads. Looks like I might as well pull the heads off and do a...

    First attempt at welding a nut failed. I realized that part of the bolt was sticking out past the other side of the block. I tried welding a nut on that side with a washer and success. Now I am able to get it up on the engine stand and dive into it. The first thing to go was the harness...

    I am officially a member of the LS Swap Club. I picked up a complete LM7 out of a 2001 Chevy Tahoe with 170k miles from the harness and computer all the way down to the transfer case. Everything drove and ran like it should. This was a deal of the century. I gave 2 crisp new Benjamin’s for it...

    Getting closer and closer… the cab does in fact need to come up another inch or so in the front. Before I pulled the cab off and the frame out to free up the shop I wanted to see how the front clip looked/lined up. Boy howdy this is looking sharp. I still need to come up with a name for this...

    So I rolled with it on the hockey pucks. I drilled them as close to center as I could and for good measure added some metal sleeve inserts to help keep the pucks from crumbling under stress. The original cab mounts appear to be in the correct location. I guessed and got something right or at...

    Broke out the trusty plasma cutter again and got to work cutting down the 1950s cab mounts. I found an image online for measurements and dimensions. It called for on the AD trucks center of front wheel to front edge of the cab door 31 1/8”. I marked that on the 80s frame to get as close as...

    Today I decided on a placement for the transmission “tunnel” and tacked it in. I am not sold on the placement but for what I needed to do next it had to be. Which was setting the cab on the frame to figure where the cab mounts need to be. I know the cab is too far forward but I had to start...

    Not a lot done this week on the cab. I made a deal with my wife that I cannot buy anything for this project unless I work an OT day which are usually Sundays. Today I stayed home so nothing new and exciting for it ☹️ I did find a loophole though, I can still work on it This afternoon, after...

    I squared everything up for the front cross bar. Equal measurements everywhere. Remember kids, measure twice cut once er weld once lol Once the front was tacked I cut my side rails and tacked them in. I learned from others not to have them as close to the edge of the rocker. Allowing a small...

    Here comes a photo dump, I’ve been busy with the cab :p I finally found a great use for my plasma cutter. If you don’t have one I suggest investing in one! Made this job 10x easier. I was able to use it to cut out the original front support. Something my cut off wheel/grinder would’ve had...

    I know I should be working on JW but something with this just said I need worked on. I’ll probably hit a wall soon and be back working with JW.

    I went to the local steel shop and bought some 2x1 14g rectangle tubing to use for the floor supports. I ended up getting enough to do the floor and build a cart for the cab. This should make life easier having it up off the ground and being able to move it out of the way when not working...

    The floor is gone in the new cab but there is a solid foundation for me to work with. Since I’m having to lift and move the cab around a bunch I needed to brace the front of the floor pan area to keep everything square. Tacked in a 3/4 pipe I had laying around. Just for fun I wanted to...

    I found another cab out in KS that is better suited for this project. The front clip was still good on the ‘49 and all the cabs are the same for all series AD trucks so it should bolt up with no issues. Here is the mock up of the 2 together.

    Time to revive this thread but I’ve been busy bouncing around between projects. I finally got around to pulling this truck out of the weeds since I started this back in ‘21. I think I bit off more than I can chew with this project. It looks innocent right? Well turns out the cab is...

    Bought a mid ‘70s c30 frame yesterday. Truck frame came out of Tulsa and is in pretty good shape. Has a sm465 trans with a 14 bolt rear and 16” wheels which is a big plus. Plans are to swap the cab over and step the rear with a custom 4 link and commercial grade bags to lower it and still...

    Head on over to YouTube and see how low the rear of my trailer sat.
