1957 GMC Blue Chip

The GMC Blue Chip and Chevrolet Task Force trucks are essentially sibling models from GM’s 1955-1959 truck lineup — they share the same platform, chassis, and mechanical underpinnings, but had distinct styling and branding differences.

Here are the key differences:

Styling & Branding:

• GMC Blue Chip featured more angular, premium styling compared to the Chevy Task Force. The Blue Chip had its own distinctive grille design and GMC badging throughout.
• 1957 specifically: The Chevrolet Task Force received a unique “more open” grille design with hood “spears” (raised ridges) that resembled the 1957 Bel Air’s styling — a look the GMC Blue Chip didn’t adopt.
• Both trucks featured the modern wraparound windshield that was a big departure from the previous Advance Design/New Design trucks they replaced.

Positioning:

• GMC was historically positioned as GM’s premium truck brand, while Chevrolet was the volume leader. The Blue Chip was marketed as the slightly more upscale option, though mechanically they were very similar.

Mechanicals:

• Both offered similar engine options, including the 235 cubic inch inline-6 and small block V8s. GMC sometimes had unique engine offerings (like Pontiac V8s in certain years), but for the most part they shared powertrains.
• Both used the same basic transmission and running gear.

1958 Update:

• Both trucks received a significant refresh for 1958 with dual headlights and wider grilles. Chevy rebranded their line as the “Apache” (while keeping the Task Force platform), while GMC kept the Blue Chip name through 1959.

Want to compare values? The 1957 GMC Blue Chip you’re looking at is listed at $30,000 — well below the market average of around $45,000 for Blue Chip trucks. The Chevrolet Task Force market averages around $55,000, so there’s some brand premium for Chevys in the collector market, but both are excellent vintage trucks!
