Chevrolet Impala 1960 images

The 1960 Impala became the best-selling car in America and held that title for a full decade — but tucked into the order form was a 348 cubic-inch V-8 with triple two-barrel carburetors making 335 horsepower, a genuine sleeper option most buyers walked right past. That’s the car serious collectors go looking for.

America’s Best-Seller Had a Secret Under the Hood

By 1960, Chevrolet didn’t just want to sell cars, it wanted to own the entire full-size market, and the Impala is exactly how it happened. Half a million buyers agreed that year, which made the Impala the single best-selling car in the entire country, a title it would hold onto for the next decade straight without interruption. Underneath those reshaped batwing fins and six round taillights, though, Chevrolet was quietly offering something almost nobody expected on a family hauler: a genuinely serious engine option most showroom shoppers never even checked the box for. So what was actually hiding under that hood, waiting for the right buyer to find it?

The Look That Redefined the Full-Size Chevy

Chevrolet reshaped and separated the Impala’s tail fins for 1960 and swapped the previous year’s “cat’s eye” taillights for six round lenses, a cleaner look that aged far better than the wilder fin era it replaced. Riding on a 119-inch wheelbase and stretching 210.8 inches long, the ’60 Impala came in four distinct flavors: Sport Sedan, Sport Coupe, four-door Sedan, and Convertible, giving buyers real choice in how formal or sporty their full-size Chevy looked. All told, Chevrolet moved 511,925 Impalas that year across every one of those body styles, a number that made it the best-selling nameplate in the country and set the tone for the entire decade that followed.

The 348 Nobody Talks About Enough

Most 1960 Impala buyers drove home with the base 235.5 cubic-inch inline six making 135 horsepower, or stepped up to a 283 cubic-inch V-8 rated at 170. But tucked into the order form was a genuine sleeper: two versions of Chevrolet’s 348 cubic-inch big-block, each fed by three two-barrel carburetors, with the milder tune making 280 horsepower and the hottest variant cracking 335. That’s a legitimate early muscle engine sitting inside a family car’s brochure, years before anyone marketed a car specifically around a big-block option. Most people picture the six-cylinder cruiser when they think of a ’60 Impala. Serious collectors are out there hunting for the 335-horse tri-power car instead, and for good reason.
