Copperhead: Stock Chevy C10 to a Blazing, Show-Stopping Street Truck
1967 Chevy C10 FULL BUILD: Building the Copperhead Street Truck from the Frame Up
Building the Copperhead, a 1967 Chevy C10, from the frame up, has been an exhilarating journey. Starting with a stock cab and frame, we transformed this classic vehicle into a stunning street truck. By integrating a mix of aftermarket parts and investing considerable effort, we turned Copperhead into an incredibly fast street machine that also boasts the aesthetics of a show truck.
The 1967 Chevy C10: A Brief History
In 1967, Chevrolet introduced a more modern look to their C10 series, along with the new nickname “Action Line.” This revision marked the beginning of a significant transformation in the C/K truck lineup, as General Motors started incorporating comfort and convenience features previously unseen in their work-oriented vehicles.
The Evolution of the C10: Comfort and Convenience
The majority of the 10 series and some 20 series Chevrolet trucks from 1967 to 1972 featured a coil spring trailing arm rear suspension. This design greatly improved the ride quality compared to traditional leaf springs. However, leaf spring rear suspensions were still available and were standard on the 30 series trucks. For GMC-branded trucks, leaf springs were standard in the rear, with the coil spring/trailing arm design offered as an option. All two-wheel-drive trucks boasted independent front suspension, while four-wheel-drive models retained a conventional solid axle with leaf springs.
Unique Features of the 1967 Model
One of the unique features of the 1967 C10 was the “small rear window.” This design was exclusive to this model year, with the larger rear window (RPO A10) available as a factory option. This small rear window gave the 1967 C10 a distinctive look compared to later models.
Standard and Optional Drivetrains
The standard drivetrain for the 1967 C10 included a three-speed manual transmission and one of two engines: the 250” straight-six or the 283 cu in (4.6 L) V8. Optional transmissions ranged from various four-speed manuals to the Powerglide two-speed automatic and the Turbo-Hydramatic 350 and 400 three-speed automatics. For those seeking more power, the 292 six and the 327” V8 were available as optional engines. The 10-series trucks came with a 6 x 5.5–inch bolt pattern, while the 3/4 and 1-ton trucks featured an 8 x 6.5–inch bolt pattern.
Notable Changes in the 1968 Model
In 1968, several changes were introduced to the C10 series. Side-marker reflectors were added to all fenders, and the small rear window cab was no longer available, except on the C40 and C60 medium-duty trucks. The GMC grille was revised, removing the embossed “GMC” letters from the horizontal crossbar. A new Custom Comfort and Convenience interior package was introduced, positioned between the Standard cab and the CST cab options.

Celebrating 50 Years of Chevrolet Trucks
To commemorate 50 years of manufacturing trucks, Chevrolet released a special 50th Anniversary package in 1968, featuring an exclusive white-gold-white paint scheme. This special edition highlighted Chevrolet’s rich heritage in truck manufacturing and underscored the importance of the C10 series in their lineup.
New Engine Options and the Longhorn Model
Also in 1968, Chevrolet added the 307 and 396 CID V8 engines to their lineup. Additionally, they introduced the Longhorn model for 3/4-ton trucks, which featured a 133-inch wheelbase, adding an extra six inches to the bed. Interestingly, Longhorns were only available as two-wheel-drive models; no factory Longhorn 4×4 trucks were built.
Building Copperhead: The Vision
Our goal with the Copperhead build was to blend the classic aesthetics of the 1967 Chevy C10 Truck with modern performance enhancements and show-quality looks. Starting from the stock cab and frame, we meticulously selected aftermarket parts that would enhance the truck’s performance without compromising its vintage charm.
Frame and Suspension Modifications
The foundation of any great build is a solid frame and suspension system. For Copperhead, we upgraded the stock frame to handle the increased power and performance modifications. We opted for a modern coil-over suspension setup to improve handling and ride quality, giving Copperhead the agility of a modern sports car while retaining its classic truck appeal.
Engine and Transmission Upgrades
To turn Copperhead into a true street machine, we needed a powerful and reliable drivetrain. We chose a high-performance V8 engine, paired with a modern automatic transmission, to provide the necessary horsepower and torque. This combination ensures Copperhead can accelerate quickly and handle high speeds with ease, making it a formidable presence on the road.
Exterior Enhancements
A show truck must look as good as it performs. For Copperhead, we focused on creating a sleek, modern exterior while preserving the classic lines of the 1967 C10. We customized the body with a unique paint scheme, blending vintage and contemporary styles. High-quality chrome accents and modern lighting elements were added to enhance the truck’s visual appeal.
Interior Comfort and Technology
Inside Copperhead, we aimed to combine comfort with cutting-edge technology. We installed custom seats upholstered in premium materials, along with a state-of-the-art sound system and modern infotainment features. The interior design pays homage to the truck’s vintage roots while offering the conveniences expected in a contemporary vehicle.
Final Touches and Testing
The final stage of the Copperhead build involved meticulous attention to detail. We ensured that every component was perfectly aligned and functioning correctly. Extensive testing on both the road and track allowed us to fine-tune the performance and handling, making sure Copperhead met our high standards.
The Copperhead Experience
Driving Copperhead is an exhilarating experience. The combination of classic design, modern performance, and show-quality looks makes it a standout vehicle. Whether cruising through city streets or showcasing it at car shows, Copperhead turns heads and draws admiration from enthusiasts and casual observers alike.
Conclusion
Building the Copperhead street truck from a 1967 Chevy C10 has been a rewarding journey. Starting from a stock cab and frame, we transformed this classic truck into a high-performance street machine that also shines as a show truck. The blend of vintage charm and modern enhancements makes Copperhead a unique and captivating vehicle, celebrating the legacy of the 1967 Chevy C10 while pushing the boundaries of what a street truck can be.
