Dreaming of a Custom 1980 Chevy K5 Blazer Build

When Jim was growing up in the ’80s he was a huge fan of the lowered Blazers and always wanted one of his own. As we all know life happens and Jim never had the chance to focus on himself and prioritize his dream. Now many years later and after becoming a leader in the construction industry, it was time for Jim to project manage his dream and build his Blazer.

From Stock K5 Blazer to Custom Performance Build

First step was to find the right Blazer. After shopping around for several years and attending several auctions Jim still was not able to acquire a K5 he needed to start this project.

After some time had passed while looking on the internet, he found one at a consignment company that was out of state. The distance made it hard for Jim to move fast on the purchase.

He called and expressed interest but never received communication back in time. Several days later he noticed online that it had already been sold. The frustration Jim had was unbearable and casted a cloud on his upcoming family vacation.

As time went by, the day when his vacation was fast approaching and during the hectic-ness and packing, guess what happened next?

The Blazer that he wanted from the consignment company arrived at his front door. To surprise his wife Kimberly had secretly bought it and had it shipped to the house arriving 45 minutes before they were set to leave for the airport.

Jim was speechless but had no time to let it sink in of what just had happened. He took a quick drive around the block with the biggest smile on his face and had to quickly park it the garage and head to the airport.


What a great start to his vacation knowing that his dream K5 Blazer was finally his and waiting for him at home.

With the support of his wife Kimberly, once they returned home, they began making a list and pulling the triggers to build the dream truck that Jim had always wanted.

The big questions still needed to be answered: Did Jim know what he was getting into? How long would this build take? How much would it cost? Would it all come together the way they wanted?  Let’s see how all of this turns out.

FROM STOCK TO NOT

Jim started with a stock 1980 Chevrolet K5 Blazer 2WD.

Engine & Performance:

  • The first thing on the list was to swap out the original V-6 to a V-8.
  • He located a 2009 Chevrolet 502 Deluxe crate engine provided by Chevrolet Performance and Jim pulled the V-6 out quickly.
  • The new V-8 came with forged aluminum pistons with a compression ratio of 9.6:1, and with the new connecting rods he was set up for success.
  • This new heart was connected to a turbo 350 transmission, which we all know delivers the power especially when it’s connected to modified 12 bolt posi rearend.
  • Now toward the front and on the top of the engine, Jim decided to go with the Edelbrock Performer carburetor.
  • To get the most bang for his buck, he went with Holley headers and stainless steel 3-inch Flow Master exhaust with cutouts. This Blazer sounds scary going down the road.

Perfect Low Stance & Wheels

Now let’s talk about adjusting the stance:

  • We all know that the stance of a custom vehicle is one of the most important decisions.
  • Well, we already know that Jim likes everything low with the least amount of clearance, but how would he achieve his dream look?
  • As you can see, he went with a lowering kit provided from Belltech which gave his K5 the best stance possible and added the perfect wheel and tire package.
  • He selected Raceline Wheels “Tumbler” series putting a 22×9 in the front and a deep 22×11 in the rear and by adding the redline tires Jim gave his Blazer an old school Hot Wheels look.

Classy Exterior Design

Next on Jim’s list were the exterior colors. This can be a hard choice since these colors always define the overall style of a build, so Jim and Kim had to decide if they wanted subtle or crazy custom designs. As you can see, they went with a couple classy colors with the nostalgic two-tone design.

The exterior colors they selected were:

  • A deep Root Beer Brown with the classic insert being painted Polar White, which are both PPG colors. The factory chrome trim ties it all together.

I have to say that I love the fact that Jim kept the factory bumpers and grille, which keeps the authentic look front and center.

Premium Hand-Crafted Interior

After making some major decisions on the powerplant and the exterior finishes, it’s time to move on to the interior.

This is where comfort meets the road, because no matter how cool your truck is, if you’re not comfortable behind the wheel you won’t enjoy driving it. I have to say that Jim will not have a problem.

The interior design and selections are phenomenal. Jim knew that he wanted to have a two-tone combo but wasn’t sure on how to achieve his dream interior. So, what did Jim do?

He turned to Old Town Upholstery in Escondido, California, and let them run with it.

  • They went with a distressed tan and brown leather, which is a great contrast to the Dark Root Beer exterior and the interior lower dash frame.
  • As you can see, a lot of hours went into this interior with the custom woodwork, mitering and routing, and the subtle pieces of acrylic. C
  • Check out the custom stitching—and let’s not forget the matching travel bag.

So, after seeing Jim’s dream K5 Blazer come to life, I would have to say, “Well done!” Not only has Jim maintained the classic K5 look, but he also also kept it clean and classy.

Jim and Kimberly go to many events, such as Goodguys, C-10 Nationals, and South Eastern Truck Nationals. So, if you’re ever at one of these events go find Jim and take a look at this well-built gem and give him a big thumbs up for achieving his goal.
