When Brian Rogers set out to build his dream truck, he faced a dilemma many enthusiasts know well: he loved the timeless styling of the classic Chevy squarebody, but he also wanted the comforts, technology, and drivability of modern trucks. His solution? Create a one-of-a-kind fusion — a 1991 Chevrolet K20 blended with a 2020 Chevy platform.

The name says it all: K2020 — a perfect mix of old-school muscle and new-school refinement.

From Vision to Reality

This wasn’t a bolt-on build. Brian sourced five different donor trucks to bring his vision to life. Starting with a 2020 rolling chassis that still had the engine and transmission intact, he faced the challenge of merging old with new.

• The 2020 cab floor pan and firewall were used so the modern interior and body mounts would align perfectly.

• Multiple donor cabs were purchased, but only a ’91 Suburban cab proved worthy of rebuilding.

• To achieve the right proportions, Brian used a standard cab’s back wall and roof skin, then stretched the cab 8.5 inches.

• Even the rear doors were stretched, giving the truck the sleek proportions of modern crew cabs.

• To complete the look, Brian added 2020 mirrors and cab lights, tying the theme together seamlessly.

Every piece of this build required custom fabrication, patience, and vision.

Engine & Drivetrain

Powering the K2020 is a 2020 Duramax L5P 6.6L V8 diesel, tuned for even more grunt.

• Stealth 67 turbo

• Wehrli Fab high-flow piping kit

• Polished stainless Jamo exhaust

• Polished driveshaft

The result is a truck that looks vintage on the outside but performs like a brand-new heavy-duty beast.

Chassis & Suspension

To make sure the ride quality matched the power, Brian upgraded the chassis with:

• 4-inch Cognito Lift Kit

• Fox 2.0 shocks (front & rear)

• Powdercoated frame & suspension in Prismatic Powders “Cheater Blue”

• Train horns with a 20-gallon tank

• Amp Research power steps

This blend of utility and showmanship ensures the K2020 is as functional as it is eye-catching.

Wheels & Tires

Rolling stock sets the stance, and Brian went big:

• 24×14 TIS wheels front and rear

• Wrapped in 37×13.50R24 tires

The deep lip, aggressive offset, and towering sidewalls make a statement from every angle.

Body & Exterior Mods

Every inch of the K2020’s exterior has been touched, blending vintage lines with modern design:

• Steel 4-inch cowl hood

• 2020 firewall & floorpan

• Cab stretched 8.5 inches, including reskinned roof

• Extended rear doors for modern proportions

• 2020-style mirrors & cab lights

• Finished in a Grey and Blue two-tone, laid down by Railroad Customs in basecoat/clearcoat

The bodywork alone is a masterclass in metalwork and fabrication, creating a truck that truly doesn’t exist anywhere else.

Interior & Technology

Inside, the K2020 feels like a 2020 Chevy, thanks to the donor’s cab components:

• 2020 dashboard, gauges, console, and steering wheel

• Stock 2020 head unit integrated with Triton Audio amps and speakers

• Recovered leather upholstery by Wrap It Up Interiors

• 20% window tint for a subtle, modern look

It’s a surreal experience: sit inside, and you’re in a new Silverado. Step outside, and you’re staring at a squarebody legend.

Build Cost, Time & Teamwork

This masterpiece wasn’t a quick weekend project.

• Build Cost: Over $190,000 invested

• Timeframe: 2 years from start to finish

• Assistance: Fabrication and assembly help from Greg Adams, Zach Adams, and Jordan Blackard

• Paint & Body: Jacob Neuenschwander of Railroad Customs

• Additional Contributions: Scorpion Coatings (bedliner), TIS Wheels, Mint Tint, Dailey’s Detailing, Jamo Exhaust

Future Plans

While Brian loves his K2020, his future vision is to sell the truck at Barrett-Jackson and build another — “not as nice, so I can daily drive it.”

Previous Builds

Brian isn’t new to ambitious projects. His past builds include “Stroked-N”, a 1948 Ford 8N tractor with a 7.3 Powerstroke, twin turbos, and nitrous — proof that his creativity and skills have always pushed boundaries.

Brian Rogers’ K2020 is more than just a build—it’s a blueprint for what’s possible when classic styling meets modern engineering. With squarebody trucks at an all-time high in popularity, this truck stands apart as a fully reimagined piece of automotive art. It’s equal parts showpiece, workhorse, and dream come true.
