American Muscle: Red, White, Blue

In 1964, Chevrolet introduced the Chevelle Super Sport (SS). It was a bold, mid-size, rear-wheel-drive coupe with powerful V8 engines and an affordable price. Performance options included notable small- and big-block V8s, such as the 396 and later the 454 cubic-inch, delivering the straight-line speed that appealed to muscle car buyers.

Chevelle’s Significance

At the height of the muscle-car wars, the Chevelle SS became a benchmark. In the late 1960s, especially 1968–1970, it was highly competitive on streets and strips, rivaling the GTO, Road Runner, and Charger. The Chevelle SS demonstrated Detroit’s ability to blend daily use with race-inspired performance, helping popularize high horsepower among mainstream buyers. In the 1970s, stricter emissions standards, rising insurance costs, and the oil crisis reduced cars’ performance across the industry. The Chevelle SS’s evolution during this era mirrored the wider muscle-car story—a shift from raw power to styling, comfort, and compliance, making it a useful lens for understanding the end of the classic muscle-car era.

The Cars

The Backstory: When Michael Mirra called the AACA Museum to donate his prized 1970 Chevelle SS 396 Convertible and 1965 tri-power GTO Convertible, curator Stan Sipko was skeptical. Few would part with such rare classics. After learning Michael was terminally ill and wanted his cars preserved, Stan agreed, and the donation was finalized after a heartfelt visit. Shortly after, Michael slipped into a coma and passed away, but his wish was honored as his father arranged for the cars’ transfer. Mirra’s selfless act ensures his beloved muscle cars are now preserved for the public to enjoy at America’s Transportation Experience–AACA Museum, leaving a lasting legacy for future generations.

WHITE: 1966 Chevrolet Chevelle SS

The Backstory: This first-generation model (1964-1967) was customized and styled to pay tribute to motorsports hall of famer and drag-race champion Bruce Larson’s USA-1 cars. When Chevrolet introduced the1966 Chevelle SS, it made waves with its all-new “coke-bottle” shape, bold rear fender contours, and wider grille, setting a new style standard for muscle cars. This was also the first year the Super Sport (SS 396) became its own series, featuring a robust 396-cubic-inch V8, with up to 375 horsepower. The SS 396 stood out with its blacked-out grille, unique badging, simulated hood scoops, and color-accented moldings. Inside, it boasted bucket seats, a center console, and a standard tachometer. With stiffer suspension, larger brakes, and nearly 440,000 units sold (according to Motor Trend), the 1966 Chevelle became a high-performance icon and a defining force in the muscle car era.

BLUE: 1970 Chevrolet LS6 Chevelle SS454 in Original Fathom Blue

Museum Collection: Donated by Scott Milestone, Rockville, MD

The Backstory: Likely one of the greatest muscle car finds ever, this 1970 Chevrolet LS6 Chevelle SS was pulled from one of collector Donald Schlag’s 21 “muscle car find” trailers discovered in De Pere, Wisconsin, in 2007. After Schlag passed away, Larry Fisette purchased the entire group of trailers, not knowing the full extent of what was inside. When the trailers were finally opened, they revealed two 1970 Chevelle SS 454s and a treasure trove of valuable parts. Scott Milestone, who later acquired this car and its associated collection, generously donated the pristine LS6 Chevelle—with original paint and interior and only 46,300 miles—to the Museum. The 1970 model represents the second generation of the Chevelle (1968–1972). The 1970 LS6 454 models are legendary.

The Legacy

Today, the Chevelle SS remains one of the most recognizable and collectible muscle cars, symbolizing an era when power, affordability, and spirit defined American motoring thanks to its clean, aggressive styling and association with peak American V8 performance.
