Exterior Aesthetics: A Masterpiece of Mid-Sixties Design

The '66 Impala SS distinguished itself with a clean, unadorned body that exuded sophistication and power. Its long, flowing profile, subtle fender skirts, and unique grille design contributed to its timeless allure.

• Front End: A prominent, full-width grille with integrated headlights, often featuring a blacked-out treatment on SS models, provided an aggressive yet refined face.
• Body Lines: The car maintained the "Coke bottle" styling introduced in 1965, with subtle curves over the rear wheels that gave it a dynamic, ready-to-pounce look.
• Rear Styling: Triple taillights on each side, a signature Impala trait, were elegantly housed within a chrome bumper, reinforcing its premium positioning.

Stepping inside a 1966 Impala SS, one finds a cabin that balances sporty intentions with surprising comfort. Our analysis shows that the SS models offered a more upscale feel compared to standard Impalas.

• Bucket Seats: Standard SS models featured front bucket seats and a center console, enhancing the sporty ambiance.
• Dash Layout: A well-organized dashboard housed clear instrumentation, including a 120 mph speedometer and optional tachometer, catering to the performance-oriented driver.
• Material Quality: While not luxurious, the interior materials were durable and well-appointed for the era, designed to withstand spirited driving while offering reasonable comfort for longer cruises.

Distinguishing SS Badging and Trim

Specific badging and trim elements set the SS apart from other Impala variants. These details were crucial for identifying the performance pedigree of the vehicle. — Islanders Vs. Flyers: Game Preview & Predictions

• Body-Side Trim: Unique body-side moldings and often a brushed aluminum tail panel trim further differentiated the Super Sport models.

Under the Hood: Engine Options and Performance of the 1966 Impala SS

At the heart of the 1966 Impala SS was its potent range of engines, from robust small-blocks to fearsome big-block options. These powertrains defined its muscle car credentials and offered varying levels of exhilarating performance.

Small-Block Powerhouses: Versatility and Driveability

The small-block V8 engines provided a balance of performance and fuel efficiency, making them popular choices for many Impala SS buyers.

• 283 V8: A dependable option producing 195 hp, suitable for those seeking a stylish cruiser with adequate power.
• 327 V8: Available in multiple configurations, including a 275 hp variant, this engine offered a significant bump in performance, making it a lively performer for its size. In our testing, the 327 consistently delivered a satisfying blend of torque and rev-ability.

Big-Block Dominance: Unleashing Raw Power

For those craving unadulterated power, the big-block engines truly solidified the 1966 Impala SS's position in the muscle car pantheon. These engines were designed for maximum output and quarter-mile prowess.

• 396 Turbo-Jet V8: Offered in 325 hp (L36) and 360 hp (L78) versions. The L78, in particular, was a high-performance legend, featuring solid lifters and a four-barrel carburetor, known for its incredible top-end power. Many enthusiasts consider the 396 a benchmark of period performance.
• 427 Turbo-Jet V8: The pinnacle of Impala SS performance, available in 390 hp (L36) and 425 hp (L72) forms. The L72, often equipped with special heads and a high-performance camshaft, turned the Impala SS into a true street beast. This engine required a serious driver and commanded respect on the road.

Transmission Options: Matching Power with Control

To complement the powerful engines, Chevrolet offered a range of transmission options, allowing buyers to customize their driving experience.

• Manual Transmissions: 3-speed and 4-speed manual transmissions were available, with the Muncie M20, M21, and M22 (Rock Crusher) 4-speeds being highly sought after for performance applications.
• Automatic Transmissions: The 2-speed Powerglide and 3-speed Turbo-Hydramatic (TH400) automatic transmissions provided smooth, reliable shifting, particularly the TH400 which was robust enough to handle the immense torque of the big-block engines. Real-world applications demonstrate the TH400's durability in high-performance settings.

Driving Experience: What It's Like Behind the Wheel of a '66 SS

Driving a 1966 Impala SS is an experience that transports you back in time, offering a unique blend of vintage charm and raw power. The feeling is distinct from modern vehicles, requiring a different approach and appreciation.

Handling and Ride Quality: Cruising and Performance

Despite its size, the Impala SS offered a surprisingly competent ride for a large American car of its era. It was designed to cruise comfortably but could also handle spirited driving when called upon.

• Suspension: Independent front suspension with coil springs and a solid rear axle with coil springs provided a relatively smooth ride. However, don't expect modern sports car handling; there's noticeable body roll during aggressive cornering.
• Steering: Power steering was a common and highly recommended option, making the large car much more manageable. Our experience indicates that unassisted steering can be quite a workout, especially at low speeds.
• Braking: Standard four-wheel drum brakes were typical for the time. While adequate for daily driving, they require a longer stopping distance than modern disc brakes. Many owners opt for disc brake conversions for improved safety and performance, a modification often recommended by industry leaders in classic car restoration.

The Soundtrack of Muscle: Engine Noise and Exhaust Note

One of the most captivating aspects of the '66 Impala SS driving experience is the visceral engine sound. The rumble of a small-block or the thunderous roar of a big-block is an integral part of its identity.

• Big-Block Roar: The 396 and 427 engines, especially with performance exhaust systems, produced an intoxicating, guttural exhaust note that announced their presence long before they were seen. This iconic sound is a key reason for their enduring appeal.
• Small-Block Thrum: While less aggressive than their big-block siblings, the 327s still offered a satisfying V8 thrum, indicative of American performance.

The Nostalgia Factor: Connecting with Automotive History

Driving a 1966 Impala SS is more than just operating a vehicle; it's a journey into a golden age of American automotive design and power. It evokes a sense of nostalgia that few modern cars can replicate.

• Community Connection: Owners often find themselves part of a passionate community, sharing stories and expertise. Forums and car shows dedicated to classic Chevrolets are vibrant hubs for these enthusiasts.
• Simpler Times: The lack of complex electronics and driver-assist features provides a raw, unfiltered driving experience that some find incredibly liberating. It’s a car that demands attention and rewards engagement.
