The 1967 Chevrolet Impala stands out as a high-water mark for full-size American automotive design. While compact muscle cars grabbed headlines, this large cruiser combined aggressive styling, massive V8 performance, and everyday practicality in a way few other vehicles managed. General Motors sold hundreds of thousands of units that year, cementing the car's place on American roads. Today, it commands respect at car shows and commands attention from collectors worldwide.
Understanding why this specific model year remains so popular requires looking past its pop-culture fame and examining its actual engineering, body styling, and powertrain options. From the sweeping coke-bottle waistline to the brute force of the available big-block engines, the 1967 model year marked a definitive evolution from the boxier styling of the early decade into sleek, aerodynamic muscle.
The Design Shift: The Coke-Bottle Aesthetic
Chevrolet completely redesigned its full-size line for the 1967 model year. The most striking change was the adoption of the "coke-bottle" styling profile. This featured sculptured body sides, curved side glass, and a fastback roofline on sport coupe models that gave the car a sense of motion even when parked.
The front fascia featured a wraparound bumper that enclosed recessed headlights on upscale trims, while the rear introduced unique triple taillights—a signature Impala trait, though shaped differently than previous years. Designers integrated curved contours that minimized the visual bulk of a car stretching over seventeen feet long.
Structural Engineering and Safety
Beneath the new sheet metal, Chevrolet updated the perimeter frame to improve ride quality and passenger protection. Engineers incorporated side-guard door beams and an energy-absorbing steering column, responding to the growing demand for automotive safety features in the late 1960s.
Weight management remained a challenge for full-size sedans. Depending on the body style and engine choice, the car tipped scales between 3,500 and 4,000 pounds. Despite this heft, the refined suspension geometry—utilizing a four-link rear setup with coil springs—delivered a remarkably smooth ride on highways while controlling body roll better than its predecessors.
Powertrain Lineup: From Economy Six to Big-Block Power
Buyers faced a massive menu of engine options when ordering a new Impala. The lineup spanned from basic utility powerplants to track-ready performance blocks.
- 250 cubic-inch inline-six: Rated at 155 horsepower, this engine catered to fleet buyers and those prioritizing fuel economy over straight-line speed.
- 283 and 327 cubic-inch small-block V8s: The 283 pushed 220 horsepower, while the 327 scaled up to 275 horsepower. These engines served as the sweet spot for daily drivers, offering a blend of reliability, maintenance ease, and decent passing power.
- 396 and 427 cubic-inch big-block V8s: For enthusiasts, the heavy-hitting big blocks delivered up to 385 or even 425 horsepower. The 427 turned the full-size cruiser into an unexpected straight-line competitor.
Transmission pairings included a three-speed manual column shift, a four-speed floor-shifted manual, the two-speed Powerglide automatic, and the robust Turbo-Hydramatic three-speed automatic. Power steering and power front disc brakes were available as options, significantly improving handling for models equipped with heavy big-block engines.
The Legend of the Super Sport (SS)
The Impala Super Sport package represented the peak of sporty styling for the brand. For 1967, the Impala SS sported unique exterior badges, distinct interior trim with bucket seats, and a center console.
The standalone RPO Z24 option code introduced the SS427 package. This version featured a specialized hood with faux louvers, heavy-duty suspension components, red-stripe tires, and the formidable 427-cubic-inch V8. While production numbers for the true SS427 were relatively low compared to standard hardtops, these models now command the highest values among serious collectors.

Restoring and Driving a Vintage Impala Today
Finding a survivor or project car requires careful inspection. Because these vehicles featured complex curved panels and substantial body mass, rust is the primary enemy. Common trouble spots include the rear quarter panels, trunk floors, lower front fenders, and frame rails near the rear wheels.
Common Restoration Pitfalls
- Ignoring Frame Rot: A straight body means little if the perimeter frame has structural rust compromises. Always inspect the frame where it curves over the rear axle.
- Incorrect Trim Pieces: Finding specific 1967-only exterior trim, side moldings, and interior bezels can prove difficult and expensive. Look for cars with complete trim packages.
- Overlooking Cooling Systems: Big-block V8 models generate substantial heat. Upgrading to a modern aluminum radiator with an electric fan is a common and necessary modification for modern driving conditions.
