Classic Chevrolet K5 Blazers are no strangers to custom builds, although few receive the level of attention seen in this remarkable 1973 example from DWS Classic Restorations. Built as a personal project before eventually finding a buyer, the SUV blends vintage styling with modern performance in a package designed to excel on both the street and the track.
Rather than restoring the Blazer to factory condition, DWS transformed it into a pro-touring machine with serious capability. The lowered stance, aggressive wheel fitment, and carefully integrated upgrades give it a purposeful appearance without losing the character of the original square-body design.
Power comes from a supercharged GM LSA V8 paired with a six-speed manual transmission, creating a combination that appeals to enthusiasts who still enjoy rowing their own gears. According to builder Darren, the drivetrain delivers well over 600 horsepower, providing the muscle needed to match the chassis upgrades underneath.
Featured on the AutotopiaLA YouTube channel, the build showcases how thoughtful engineering and attention to detail can elevate a classic truck. Nearly every component has been reworked, resulting in a Blazer that looks factory-inspired while hiding an impressive amount of custom fabrication.
Built to Perform, Not Just Impress
The project began unexpectedly when DWS decided to turn a shop-owned 1973 Blazer into something special during a quieter period at the workshop. Once modifications to the rear wheel tubs began, the vision quickly evolved into a complete performance build.
Support from several aftermarket companies helped shape the finished product, with the truck eventually serving as a development vehicle for new suspension components. The rear suspension was created alongside TCI Engineering, and the resulting design became the foundation for a production kit now available for classic Blazers.
The chassis also received extensive reinforcement, including internal frame bracing to increase rigidity. Although the truck has only seen limited track time, Darren noted that it exceeded expectations even before the suspension was fully dialed in.
Supercharged LSA Power Meets Modern Chassis Hardware
Under the hood sits a stock GM LSA supercharged V8 sourced from a wrecked Camaro, backed by a six-speed manual gearbox that Darren had already planned to use. Keeping the manual transmission was an easy decision due to his preference for a more engaging driving experience.
The Blazer retains a narrowed Chevrolet 12-bolt solid rear axle to accommodate its massive rear tires while maintaining durability. Stopping power comes from a complete Wilwood braking system featuring six-piston front calipers, four-piston rear calipers, and large rotors at each corner.
A stainless 3-inch exhaust system with Flowmaster 50-series mufflers gives the truck a muscular soundtrack without becoming overwhelming. Custom headers are tucked tightly beneath the chassis to preserve valuable ground clearance despite the Blazer’s lowered ride height.
Custom Details Throughout the Build
The exterior combines subtle refinements with functional improvements. The factory-style bumpers remain in place, although the rear bumper has been repositioned closer to the body using custom brackets and a handmade filler panel for a cleaner appearance.
One of the more distinctive touches is the smoothed removable hardtop, replacing the factory textured finish with sleek bodywork. The graphics package also pays tribute to Chevrolet’s 1970s Indy 500 pace truck, giving the Blazer a period-inspired accent without overwhelming the overall design.
Functionality wasn’t overlooked either. Aircraft-grade acrylic rear quarter windows incorporate NACA ducts that channel air toward the rear brakes, while additional front brake cooling ducts are integrated into the front fascia. Even these race-inspired features are blended seamlessly into the truck’s appearance.
Massive Triumph Forged wheels complete the stance, measuring 20×9 inches up front and 20×12 inches at the rear. Wrapped in 245-section front tires and enormous 335-section rear rubber, the combination gives the Blazer the planted look expected from a serious pro-touring build.
A Driver-Focused Interior
Inside, the cabin balances modern convenience with classic Chevrolet styling. Dakota Digital gauges occupy the original instrument locations, while a custom center console houses navigation and infotainment without distracting from the vintage dashboard.
Reupholstered Corbeau seats, custom billet pedals, leather trim, and bespoke DWS badging add a premium feel throughout the cabin. A chromoly rear half cage, custom rear seating, and five-point harness provisions reinforce the truck’s performance-focused mission while maintaining practicality.
During the road test, the Blazer impressed with its refined ride quality, responsive handling, and unmistakable supercharger whine. Although the new owner was about to take delivery, preventing any full-throttle demonstrations, the brief drive still highlighted just how complete the build had become.
With meticulous craftsmanship, modern performance, and carefully integrated custom touches, DWS Classic Restorations created a 1973 Chevy Blazer that successfully bridges classic truck styling and contemporary driving dynamics.
