The debut of Jet Age styling
The market for pickups was booming in 1960 and the emphasis on styling, comfort, and power was stronger than ever. “All major manufacturers vied for a piece of this expanding pie,” said Mike McNessor in a Jan. 2021 report in Hemmings Classic Car.
The evolution of the Chevrolet Task Force and GMC Blue Chip trucks during the 1950s helped popularize many features that are commonplace today, McNessor said. Among the new features were fleetside boxes, V-8 engines, automatic transmissions and comfortable interiors.
“But, for 1960, GM upped the ante even further, implementing radical new Jet Age styling with full-width hoods accented by jet engine-inspired front air intakes,” McNessor said.
Styling of the 1960 GMC Pickup
The curves of the previous generation trucks were gone, replaced with sharper angles and creases accenting boxy cabs.
Under the skin, the 1960 GMC pickup had double-wall roof construction that included insulation between the sheet-metal layers. There were new front inner fender skirts, safety-catch door latches, sturdier hinges, and rubber insulated cab mounts. A full-length rocker panel, tied to front and rear cab supports, replaced the old-timey interior step that previous GM trucks incorporated into their floors.
For the 1960 model year, GMC was the first brand to introduce V-6 engines in pickup trucks. There was also a V-12, known as the Twin Six. (GM media archives)
1960 GMC Pickup Interior Redesign
“Inside the cockpit for ’60, there were suspended clutch and brake pedals that eliminated difficult-to-seal holes in the floor. A 26-percent increase in windshield area gave operators a better view of the road, while longer wiper blades kept more of that glass clear in stormy weather. There was nearly 6 inches more hip room, plus more shoulder room, headroom, and legroom over previous GM trucks, all in the name of driver comfort.”
Beginning in 1920, GMC and Chevrolet trucks became largely similar, according to the page in Wikipedia. Built as variants of the same platform, the two brands shared much of the same body sheetwork, except for nameplates and grilles — though their differences, especially engines, have varied over the years,
GMC boasted in print ads a “breakthrough” in truck engines “to give triple the life” without a major overhaul. (GM media archives)
A Breakthrough In Truck Engines
“GMC advertising marketed its trucks to commercial buyers and businesses, whereas Chevrolet’s advertising was directed toward private owners. Beginning in 1928, GMCs used Pontiac’s 186-cubic-inch six-cylinder engines in their lighter trucks. Medium-duty trucks relied on Oldsmobile straight-6 engines, while the heaviest trucks used GMC’s own “Standard Big Brute” engine.
“From 1939 to 1974 GMC had its own line of six-cylinder engines, first the inline sixes known as “Jimmys” from 1939 to 1959, and then their own V-6 from 1960 until 1974, of which a V-8 and a V-12 version also existed.
“Additionally, from 1955 through 1959, the less than 2-ton, domestic GMC gasoline trucks were equipped with Pontiac, Buick and Oldsmobile V-8s —whereas the Canadian models used Chevrolet engines.”
