The 1972 GMC Sierra Pickup marks the final and most refined year of the celebrated Action Line series, a generation that successfully transitioned American trucks from utilitarian tools to comfortable lifestyle vehicles. This specific short bed model, crossing the block at Indy 2026 on Thursday, May 14th, represents the absolute pinnacle of the breed. Having secured “Best Overall GMC” at the 2022 Lebanon C10 Nationals and a win at the 2023 Chattanooga World of Wheels, its pedigree is undisputed. Following a comprehensive nut-and-bolt restoration, it retains its original matching-numbers drivetrain while integrating tasteful modern enhancements for a superior street presence.
Two-Tone Olive Green and Hand-Painted Woodcraft
The exterior of this Sierra is finished in a period-correct two-tone Olive and Green palette, emphasizing the clean, horizontal lines of the short bed silhouette. Its visual character is defined by a perfect balance of classic restoration and modern custom touches, including a CPP Products lowered rear end that tucks 22-inch U.S. Mags wheels into the arches. One of the most striking details is the hand-painted woodgrain bed, which offers a bespoke artistic touch rarely seen on standard restorations. Every piece of trim and brightwork has been addressed to meet show-winning standards, ensuring it commands attention from every angle.
Houndstooth Textiles and Factory Air Conditioning
Inside the cab, the 1972 GMC Sierra Pickup features a stunning Green interior accented by iconic Houndstooth cloth inserts. This cabin serves as a masterclass in early seventies truck luxury, blending durable materials with an upscale aesthetic that remains highly sought after by modern collectors. A standout feature is the inclusion of factory air conditioning, a premium option for 1972 that ensures modern comfort during summer cruises. The interior environment remains faithful to its original design while benefiting from the same nut-and-bolt attention to detail found on the exterior, creating a seamless and high-quality user experience.
Matching-Numbers 350 V-8 and Lowered Precision
Performance is anchored by the original, matching-numbers 350 CI V-8 engine, providing the reliable small-block power that helped GMC dominate the segment. The engine is mated to an automatic transmission, delivering smooth power through a drivetrain that has been fully refreshed to “new” condition. While the heart of the truck remains stock, the chassis has been modernized with a CPP Products lowered rear end to improve handling and create a more aggressive profile. This combination ensures that the truck retains its classic mechanical soul while offering the improved road feel and stance required for a modern custom show winner.
