1972 GMC K2500 Sierra Grande: 454 Powered Retro Truck

1972 GMC K2500 Sierra Grande: 454 Powered Retro Truck This 1972 GMC K2500 Sierra Grande, retrofitted with a 454ci V8 and extensively refurbished, is a blend of classic styling and modern performance. Acquired by the seller in 2017 out of Nevada, the truck underwent a refurbishment completed in 2025. This project involved a repaint and exterior refresh, an overhauled interior, and significant mechanical upgrades. The truck, originally finished in Ochre and white, now features a dual exhaust system, a 4″ lift, 17″ Pro Comp wheels with 35″ KO2 tires, and a red oak bed floor.

Performance and 454 V8 Power: The truck is powered by a 454ci big-block V8, equipped with an electric-choke carburetor and an aluminum radiator. Long-tube headers are mated to a dual exhaust system with an H-pipe and stainless-steel mufflers, enhancing the engine’s performance and sound. Power is routed through a TH350 three-speed automatic transmission and an NP205 dual-range transfer case. The truck is also equipped with a limited-slip Dana 60 rear end, providing robust off-road capability.

Exterior Styling and Refurbishment Details: The truck was refinished with PPG paints, and its grille, brightwork, bumpers, and emblems were replaced during the refurbishment. The glass, weatherstripping, and window felts were also replaced, and the hood hinges, inner fenders, and radiator core support were powder coated. The 8′ Wideside box features a red oak floor with polished stainless-steel runners and a new gas tank beneath it. The truck rides on 17″ Pro Comp alloy wheels with 35×12.50″ BFGoodrich All-Terrain T/A KO2 tires, and the suspension features a 4″ lift with Rough Country dampers.

Interior Comfort and Modern Upgrades: The interior features a bench reupholstered in tan vinyl with houndstooth inserts and fresh carpets. A replacement headliner, dashboard pad, and Vintage Air climate control with heating and air conditioning enhance comfort. Pioneer speakers are wired to a Bluetooth-capable Pioneer head unit with a USB port. A three-spoke steering wheel is mounted on a refurbished tilt column, and the five-digit odometer shows 13k miles, having rolled over once, with approximately 300 miles added under current ownership.

Custom Build and Modern Upgrades: This 1972 GMC K2500 Sierra Grande, with its 454ci V8 engine, 4″ lift, and modern interior upgrades, is a unique blend of classic truck style and contemporary features. The refurbishment has resulted in a well-equipped and visually striking vehicle, offered in California with parts receipts and a clean Idaho title.
