The 1972 GMC K2500 4×4 represents the final evolution of GM’s first-generation K-series before the square-body redesign arrived. This refurbished example pairs classic Wideside styling with a BluePrint 383ci stroker V8 installed in 2020. Rebuilt drivetrain components and revised axle ratios position it as a modernized heavy-duty pickup with period character.
Exterior Design
The truck was refinished in orange under prior ownership, emphasizing its upright stance and squared fenders. A Wideside bed, crosshair grille, and quad headlights define the front fascia. Chrome bumpers add contrast, while side steps improve access. Furthermore, a suspension lift and 35-inch BFGoodrich tires create a purposeful off-road silhouette.
Interior
Inside, the cabin retains a straightforward work-truck layout with a black-trimmed bench seat. Door-mounted armrests and a heater maintain factory-style utility. However, an aftermarket steering wheel and updated gauges modernize driver touchpoints. A Kenwood stereo replaces the original unit, adding contemporary audio capability without altering the dash structure.
Performance
Power comes from a BluePrint 383ci V8 featuring aluminum heads, a Holley 750cfm carburetor, and a dual-plane intake manifold. Internal components include a cast steel crankshaft, hypereutectic pistons, and a Melling oil pump. Output figures are not specified in the listing, though a 2020 dynamometer report accompanies the truck. A rebuilt Turbo 350 three-speed automatic and dual-range transfer case manage torque delivery.

Revised 3.73:1 gearing in both differentials sharpens acceleration and improves off-road tractability. Power steering and a replaced steering gearbox enhance control. Braking comes from power-assisted front discs and rear drums. Edelbrock shocks complement the lifted suspension, supporting stability over uneven terrain.
Market Context & Rivals
In 1972, the K2500 competed with the Ford F-250 Highboy and Dodge W200 Power Wagon. Original pricing varied by configuration, typically landing below $4,000 before options. Unlike many rivals, the GMC shared mechanical architecture with Chevrolet yet carried distinct trim identity. Today, modified examples appeal to buyers seeking classic style with stronger small-block output.
Collector values for first-generation K-series trucks have risen steadily, particularly for clean 4×4 models. Restomod builds with documented engine upgrades often trade between $35,000 and $60,000 depending on execution. Consequently, well-sorted trucks like this example sit in a growing niche between restored originals and full custom builds.
Ownership & Value Trends
Ownership centers on mechanical simplicity and abundant parts support for small-block Chevrolet-based engines. The Turbo 350 remains widely serviceable and durable under moderate load. Additionally, BluePrint crate engines carry documented build specifications, adding buyer confidence. As vintage trucks continue gaining mainstream appeal, upgraded 4×4 examples show consistent long-term demand.
This 1972 GMC K2500 4×4 blends classic heavy-duty truck design with a modern 383 stroker and rebuilt drivetrain. Its lifted stance and documented upgrades position it as a usable vintage 4×4 with strengthened mechanical credibility.
