The 1972 GMC Sierra Grande marks the final and most refined year of the celebrated “Action Line” series, a generation that transitioned the American pickup from a purely utilitarian tool to a sophisticated lifestyle vehicle. This example has undergone an exhaustive frame-off restoration by the renowned Lee Butler, ensuring every nut and bolt meets a premium standard of fit and finish. Finished in a classic two-tone Blue and White, this truck successfully preserves the iconic “square-front” GMC aesthetic while integrating significant modern performance upgrades. As a Sierra Grande, the top-tier trim level for 1972, it represents the pinnacle of early seventies pickup luxury and collectability.
Two-Tone Blue and White Finish
The exterior visual character of this 1972 GMC Sierra Grande is defined by its laser-straight bodywork and the timeless combination of Blue and White paint. The frame-off restoration process is evident in the meticulous panel alignment and the deep, mirror-like quality of the finish. Chrome brightwork, including the distinctive GMC grille and heavy-duty bumpers, provides a brilliant contrast to the two-tone palette. The truck retains its classic silhouette, emphasizing the clean lines and rugged proportions that have made the 1967-1972 GM trucks some of the most sought-after pickups in the vintage market today.
Houndstooth Upholstery and Period Appointments
Inside the cabin, the Sierra Grande offers a masterclass in period-correct refinement, featuring the legendary Black and White Houndstooth cloth seat inserts. This pattern was a hallmark of high-trim GM trucks of the era and remains a favorite among enthusiasts. The interior environment is further enhanced by a wood-rimmed steering wheel and a factory-correct AM/FM radio, maintaining an authentic 1972 atmosphere. Despite its vintage appearance, the cabin provides a comfortable and spacious environment, with the restoration ensuring that every switch and gauge operates with the precision of a much newer vehicle.
HO ZZ4 350 V-8 and Turbo 350 Strength
Performance is anchored by a high-output ZZ4 350 CI GM crate engine, a significant upgrade over the original factory powerplant. This modern small-block features high-flow heads and a Holley Performance carburetor, providing a factory benchmark of 355 hp/360 PS and 405 lb-ft/549 Nm of torque. Exhaust gases are funneled through performance headers and a dual exhaust system, delivering a crisp and authoritative V-8 soundtrack. Power is funneled through a robust Turbo 350 automatic transmission, while power steering and power brakes ensure that this high-performance pickup remains manageable and effortless to drive in modern traffic conditions.
