A heavily modified 1966 Chevrolet K20 Stepside pickup is drawing attention as a unique blend of vintage utility and hidden performance, following a comprehensive refurbishment that transformed the classic truck into a capable four-wheel-drive sleeper.
Originally part of Chevrolet’s first-generation C/K truck lineup, the K20 represented a turning point for General Motors when it debuted in 1960. Built on a dedicated truck chassis, the K-series marked the company’s first in-house four-wheel-drive system, replacing earlier third-party conversions. The three-quarter-ton K20 model played a key role in establishing Chevrolet’s reputation for durable, factory-built 4x4 trucks.
The example now being offered for sale in Tacoma, Washington, has undergone significant changes under prior ownership. During the restoration process, the cab and bed were removed from the frame to allow for structural repairs. The exterior now features a patina-style finish, preserving a worn-in appearance that contrasts with the extensive mechanical upgrades beneath the surface.
The most notable modification is the addition of a 327 cubic-inch V8 sourced from a mid-1960s Corvette. This engine replaces the truck’s original powertrain, delivering a more performance-oriented character. The V8 is equipped with refurbished components, including the carburetor and distributor, while key systems such as the radiator, fuel tank, exhaust, and cooling hardware have been replaced.
Power is delivered through a T5 five-speed manual transmission paired with a dual-range Rockwell transfer case, allowing the driver to switch between rear-wheel drive and four-wheel drive. The drivetrain is supported by a 10-bolt front axle and a 14-bolt rear axle.
The truck rides on 16-inch steel wheels fitted with off-road tires and features a lifted suspension with upgraded Fox shock absorbers. Braking performance has been improved with front disc and rear drum brakes, and the steering system has also been refreshed.
Inside, the cabin combines vintage styling with modern touches. A bench seat trimmed in gold vinyl and patterned cloth is paired with updated Dakota Digital gauges and a Bluetooth-compatible stereo system. The digital odometer shows 1,400 miles, likely reflecting use since the rebuild.
Additional exterior features include a wood-floored Stepside bed, grille guard, and tow hardware, reinforcing the truck’s utility roots.
As interest in restomod trucks continues to grow, this Corvette-powered K20 stands out as a distinctive example of how classic platforms can be reimagined with modern performance while retaining their original character.
