Chevrolet Chevelle SS vs. Pontiac LeMans GTO

The mid-1960s were a special time for the American automobile, as the idea of ​​a “muscle car” was just beginning to take shape.

These were low-key performers who could usually only be spotted by subtle badges.

1966 Chevrolet Chevelle SS

Auction Dilemma: Chevrolet Chevelle SS Vs. Pontiac LeMans GTO

The Super Sport (SS) package was a brilliant formula developed by Chevy to spice up the regular Chevelle when it debuted in 1964. The performance upgrade was so well received that the Chevelle SS 396 became a separate variant along with the model year 1966. With a paint job, this Marina Blue example presents an exterior that seems worthy of a showroom. The list says 61,000 miles, but there are no details on actual mileage.

A large 396 cubic inch V8 block matching the numbers sits under the hood. Chevrolet offered three different versions of this engine in the SS with horsepower ranging from 325 to 375, but this information is missing from the eBay listing. A three-speed manual transmission manages the rear wheels of this Chevelle.

Often grappling with other divisions of GM, Pontiac has positioned itself as the performance division of the automaker. Phrases such as “Pontiac Excitation” were part of the brand’s marketing efforts. And the first use of the “muscle car” moniker in advertising was for the 1964 GTO, a car that shared GM’s A-body platform with the Chevelle. According to the seller, this 1964 GTO confirms its performance with a verifiable racing pedigree. The list also indicates that the 17,890 miles on the odometer are correct. At one point, the clean, rust-free exterior of the car was changed to Sunfire Red, a rare factory color.

Pontiac’s Tri-Power engines, like the 389 cubic-inch V8 under the hood here, date back to the 1950s. The triple-dual-carb configuration helped boost horsepower (348 horsepower for the 1964 GTO) and add to Pontiac’s performance image. A replacement Muncie four-speed manual transmission controls the rear wheels of this GTO.
