Getting behind the wheel of a vintage full-size cruiser is an exercise in scale, momentum, and nostalgia. The 1964 Chevy Impala remains a towering benchmark of mid-century American automotive design, offering a unique blend of boulevard ride quality and highway presence that modern crossovers simply cannot replicate. If you want to understand why this specific model year commands such reverence among collectors and lowrider historians alike, you have to experience how it floats down an open stretch of asphalt.
Unlike its heavily sculpted 1959 and 1960 predecessors or the crisp contours of the later restyles, the 1964 model year represented the final, refined bow for the third-generation Impala. It traded the heavy, jet-age ornamentation of previous years for clean, straight beltlines, subtle rear deck sculpting, and the iconic triple taillight clusters that defined an era. This review breaks down what it's really like to drive, maintain, and live with Chevrolet's timeless full-size legend today.
Design Heritage and Exterior Presence
The proportions of a 1964 Impala demand respect. Stretching over 209 inches long with a 119-inch wheelbase, the car occupies a footprint that dwarfs modern midsize sedans. Yet, because of its pillarless greenhouse design and low beltline, visibility from the driver seat is surprisingly expansive.
Chevrolet kept the chrome trim restrained for '64 compared to the wild styling excesses of the fifties. A narrow upper body bright molding and slender body sill molding accent the slab-sided body panels without looking cluttered.
- The Greenhouse: Thin pillars offer panoramic sightlines, making lane changes and parking maneuvers manageable despite the immense length.
- The Tail: The revised rear bumper and recessed triple taillight setup became an instant signature that enthusiasts look for immediately.
- The Stance: Sitting on 14-inch steel wheels with whitewall tires or period-correct wire wheels, the car carries a low, purposeful cruiser posture.
Powertrain Lineup and On-Road Performance
Buyers in 1964 could configure their Impala anywhere from an economical commuter to a stoplight-brawling muscle car. The engine bay welcomed everything from the dependable 230 cubic-inch Turbo-Thrift inline-six up to the legendary 409 cubic-inch V8 pushing 425 horsepower with dual four-barrel carburetors.
Most survivors you'll encounter at local car shows feature either the smooth 283 cubic-inch small-block or the immensely popular 327 cubic-inch V8, which pumped out 250 to 300 horsepower. Paired with either a three-speed manual or the two-speed Powerglide automatic transmission, power delivery is linear and relaxed.
- Low-End Torque: The 327ci engine develops 350 lb-ft of torque down low, letting the heavy chassis pull away from stops effortlessly without screaming for revs.
- Transmission Behavior: The two-speed Powerglide has a wide gap between low and high gear, meaning highway passing requires a deliberate stomp on the pedal to drop the transmission into its working range.
- Ride Quality: Coil springs and hydraulic shock absorbers soak up road imperfections with a signature highway float, though tight corners reveal significant body roll.
Interior Comfort and Practicality
Opening the heavy doors reveals a cabin built with heavy-gauge steel, durable vinyl, and polished metal accents. The swirl-pattern instrument panel and thin-rim steering wheel transport you straight back to mid-century America.
Space is a defining luxury here. Six adults can ride in genuine comfort across the front and rear bench seats. Meanwhile, the cavernous trunk swallows luggage, though its flat floor can let loose items slide around during enthusiastic cornering.
- Steering Effort: Power steering was a popular option, though vintage steering boxes often require more than five turns lock-to-lock, demanding a relaxed, anticipatory driving style rather than twitchy inputs.
- Braking Realities: Standard four-wheel drum brakes are adequate for normal traffic pacing, but hard stops from highway speeds induce fade quickly. Upgrading to modern front disc brakes is one of the most common and sensible modifications for modern street driving.
Common Mechanical Pitfalls to Watch
If you're inspecting a potential purchase or preparing to take a newly acquired Impala out for a long weekend, keep a close eye on a few recurring trouble spots inherent to vintage GM full-size cars of this vintage.
- Rust Zones: Check the lower rear quarter panels, trunk floor pans, and front frame horns where moisture accumulates. Convertible and sport coupe models are particularly susceptible to cowl rust.
- Fuel Vapor Lock: Modern ethanol-blended fuels boil at lower temperatures than vintage gasoline, sometimes causing vapor lock in carbureted big-block and small-block V8s during hot summer stop-and-go driving.
- Electrical Grounds: Faded cloth-braided wiring harnesses and corroded firewall ground straps frequently cause erratic dashboard warning lights and dim lighting.
Frequently Asked Questions
How many miles per gallon does a 1964 Chevy Impala get?
Expect anywhere from 10 to 14 MPG under mixed driving conditions. Highway cruising with a well-tuned small-block V8 can stretch up to 16 MPG, while aggressive throttle use with a high-performance 409 will easily drop fuel economy into the single digits.
Is it difficult to find replacement parts for a '64 Impala?
No. Because Chevrolet produced hundreds of thousands of full-size vehicles in 1964, reproduction sheet metal, interior trim, suspension components, and engine rebuild kits are widely available through specialized catalog suppliers like Classic Industries and OPGI.
What is the difference between a standard Impala and an Impala Super Sport (SS)?
For the 1964 model year, the Super Sport graduated from an option package into its own dedicated series. The SS package added distinct exterior side trim deletion, bucket seats, a center console, specialized engine-turned aluminum dash inserts, and unique exterior badging.
Can you install modern aftermarket upgrades without ruining originality?
Yes, restomodding is exceptionally popular for this generation. Many owners preserve the exterior aesthetic while upgrading to power front disc brakes, modern vintage-looking electronic fuel injection (EFI), updated air conditioning systems, and improved radial tires for safer, more reliable touring.
How does the 1964 Impala handle compared to modern cars?
It feels completely different. You won't find razor-sharp cornering or stiff suspension damping. Instead, you get a plush, isolation-heavy ride that requires you to brake earlier and steer with deliberate, sweeping hand movements. It trades agility for unmatched character and road presence.
