Project 1974 Chevy K5 Blazer - Building A Premudder

The First Step Of The UA Blazer Build

It was time for me to start another project. It had to be a '73-'75 Blazer for the full convertability and all-around great wheelbase, plus it was the first 4x4 I had ever owned. I had been planning on how I would build another one since I sold my original 10 yearsago, and my plan called for a crossover off-roader like nothing we have really tried before.

It couldn't be too expensive because I wasn't going to keep much of what was probably already on it. And I didn't want to be doing a restoration so it had to be pretty much rust-free. I basically needed a clean body and a frame.

Two months had passed and I had somehow bought two more trucks, neither of which would be my ultimate premudder-a cross between a prerummer and a mud truck. In desperation to get a foundation for Fabworx Off Road to start on, I accidentally found and bought the biggest Blazer pile in the world, in the middle of the night, ignoring all of my own rules about buying vehicles. I barely even turned the flashlight on before I offered the guy half of what he was asking, and later realized I had still gotten taken for a ride. It had tons of rust, it'd been rolled, it had been parted out and put back together with junk, and once we took the engine apart we would find out that the No. 1 piston had a hole in it. Awesome. I'm glad I bought such a gem to start with.

Brian McCully was such a nice happy guy when I first met him and the rest of the Fabworx crew. We'll see how much he's smiling at the end of the buildup. He and Jack Arrington were actually in the middle of pulling the entire front end off the body when I snapped this. Since the engine was going to be coming out and we had some special plans for a '98 front end on this K5, it made sense to just pull the sheetmetal before we started.

Two days later I had it at Fabworx's shop, and after the verbal berating I received for the quality piece of machinery I had bought, we were looking at the task ahead realizing that there was no real room for error with only seven weeks left to build the truck. The first thing to do was to attack the frame, fixing the horrendous cracks and shoddy repairs that occurred over the years, and get some suspension on it to hang the axles from. The next part of the plan was to pull the big-block 396ci and give it an Edelbrock spice-up while we fit the tranny, transfer case, and axles underneath it. Without a working powertrain, this truck wasn't going to go anywhere, and we were about to find out that the short block was worthless.

Yes, intentions had been good; this would be a fun thing for everyone, and we would have plenty of time to complete it. But the deeper we dug, the more work we found, and what was to be a somewhat economical and leisurely build got mighty expensive toward the end, just hours before the Ultimate Adventure started.

I think you'll like what we ended up with. The K5 (in the end) turned out to be a prerunner-themed 4x4 with mud-truck roots: It can roar 80 mph down the highway, churn big Boggers through thick mud, and hit desert whoops at 60 mph. But that's a ways off from where we are today.


I knew the steering box and frame had issues just from the testdrive, but that was a normal occurrence and I was expecting it on any '73-'87 Chevy. What I didn't realize is how bad it could actually be, and what some people would call a suitable fix. Once I actually got under to examine the frame, I was enlightened on what hackwork really was. Real hackwork is doing things like welding the power-steering box itself to the frame of the vehicle.

None of us had ever seen a Chevy frame this bad. In hindsight, we should have cut the front end off and made our own framerails. After hours of grinding off junk and cleaning multiple frame cracks, Tim Fenzel finally could put all these weld repairs in. It looks like some kind of Hobart Welder ad, doesn't it?

With the frame welded up, Arrington and Tim Fenzel were able to get started on the frame bracing. Since it was already too far gone to just use an Off Road Design steering-box brace, they had to plate the frame on both sides with 3/8-inch steel. Once installed, we would be able to put our donor steering box on and move to our donor axle and crossover steering.
