LS364/450-Powered Modified 1971 Chevrolet C20 Pickup AWD

Description

Introduced for the 1967 model year, Chevrolet's second-generation C/K truck series is widely regarded as one of the most desirable classic pickup platforms. Known for its timeless design, aftermarket support, and straightforward construction, the generation has become a favorite among restorers and custom builders alike.

This custom 1971 Chevrolet C20 was extensively modified by the seller over the course of several years. It rides on a frame said to come from a GMT800-era 2004 GMC Yukon, and it is powered by an 6.0-liter LS364/450 Gen III V8 crate engine paired with a 4L65-E four-speed automatic transmission and a permanent all-wheel-drive system.

The truck's body has been refinished in metallic blue, and it features exterior brightwork including chrome front and rear bumpers as well as a bed cover. This modified C20 rides on 20" alloy wheels from a late-model Chevrolet Silverado 1500, which sit over four-wheel disc brakes. Inside, the cab features Ram-sourced power-adjustable front seats wrapped in black fabric, which are separated by a full-length console with cupholders and storage. The color-matched steel dash features a Stinger touchscreen head unit, VintageAir controls, a CD player, USB inputs, and modern digital instrumentation behind a four-spoke steering wheel from a GMT400-era truck.

Underneath, the GMT800 frame retains an independent front suspension and a coil-sprung rear axle, and the truck features hydraulically-assisted power steering.

This modified 1971 Chevrolet C20 Pickup is now offered with a clean Ohio title in the seller’s name.

Ownership History

The seller states the truck was constructed as a four-year custom build utilizing a 1971 Chevrolet C20 body and a 2004 GMC Yukon Denali donor chassis. It is now being offered with a clean Ohio title listing it as a 1971 Chevrolet.

From the seller: "This truck was built as a complete frame-off restoration over four years. The goal was to combine the classic appearance of a 1971 Chevrolet pickup with the modern performance, comfort, and reliability of a 2004 GMC Yukon Denali platform. During the build, the body and bed were mounted to the Denali chassis, and the truck was fitted with a 6.0-liter LS364/450 Gen III V8 crate engine.

The undercarriage was restored and finished to complement the exterior, and extensive attention was given to the details throughout the build. The result is a professionally engineered custom truck that utilizes modern chassis, suspension, braking, and drivetrain components beneath classic Chevrolet styling."

Additional Information

The truck is titled in Ohio as a 1971 Chevrolet using the VIN CE231Z655836, which matches what is stamped on the door tag. An aftermarket chassis number plate has been riveted to the header panel, which lists 1GKEK63UO4J146890 and aligns with a 2004 GMC Yukon reportedly used as a donor vehicle for the build. The donor vehicle was reported to NMVTIS as having been junked and salvaged in 2019.
