1964–1967 Chevrolet Malibu SS: The First-Era A-Body That Lit the Fuse
Historical Context and Development Background
Chevrolet’s mid-size A-body arrived in 1964 as the Chevelle, slotted between the compact Chevy II and full-size Impala. Within it, the Malibu badge denoted the upscale trim, and the Malibu SS package added buckets, console, brightwork, and a sportier persona. It was General Motors’ timely answer to a rapidly forming market: Pontiac’s GTO had just rewritten the rulebook by pairing a mid-size body with V8 thrust, while Ford’s Fairlane/Thunderbolt and Mopar’s Belvedere/Satellite were proving their mettle on the strip. Corporate policy still frowned on overt racing participation after GM’s 1963 competition ban, but dealers and engineers knew where the winds were blowing.
In 1964–1965 the SS was a Malibu-based appearance and equipment package that could be paired with anything from an inline-six to a 327 small-block. The watershed came in 1965 with the RPO Z16: a limited run of Malibu SS 396s fitted with a unique heavy-duty chassis, serious brakes, and Chevrolet’s new big-block—essentially a proof of concept for what followed. In 1966, the SS graduated to its own model line as the Chevelle SS 396, while the Malibu continued as the higher-trim Chevelle. That U.S.-market shift coexisted with a Canadian-market anomaly: Canada retained a Malibu SS identity into 1966–1967, typically paired with small-block power and SS-specific trim.
Design-wise, the first-era Chevelle/Malibu combined tidy proportions with honest, clean surfacing. Underneath sat a conventional but competent architecture: double wishbones and coils up front, a coil-sprung live axle on trailing arms in back. Chevrolet tuned the SS with stiffer springs and shocks when so optioned, and the Z16 went further with a boxed (convertible-spec) frame and uprated hardware. Straight-line work, dealer tuning, and the burgeoning NHRA Stock and Super Stock classes did the rest, forging the car’s early drag-racing reputation.
Engines and Technical Specs
The Malibu SS spanned powertrains from thrifty sixes to the thumping Z16 396. Key specifications below reflect factory offerings for 1964–1965 Malibu SS and the 1965 Z16, which set the stage for the 1966–1967 SS 396 era.
| Engine | Configuration | Displacement | Horsepower (SAE gross) | Induction | Redline | Fuel System | Compression | Bore x Stroke (in) |
|---|---|---|---|---|---|---|---|---|
| 194 Turbo-Thrift I6 | Inline-six, iron block/head | 194 cu in (3.2 L) | ~120 hp | Naturally aspirated | N/A (factory redline not published) | 1-bbl carburetor | ~8.5:1 | 3.56 x 3.25 |
| 230 Turbo-Thrift I6 | Inline-six, iron block/head | 230 cu in (3.8 L) | ~155 hp | Naturally aspirated | N/A | 1-bbl carburetor | ~8.5:1 | 3.88 x 3.25 |

Driving Experience and Handling Dynamics
In small-block Malibu SS form, there’s an eagerness that belies the car’s modest footprint. The 283 and 327 spin up crisply on a good Carter or Rochester four-barrel, with throttle response that feels immediate by carb standards. The Muncie four-speed—especially with a Hurst linkage—is satisfyingly mechanical; the wide-ratio M20 works well on the street, while closer M21 gearing suits a more aggressive axle. Powerglide’s two-speed automatic is smooth and tough but blunts the small-block’s top-end sparkle.
Steering is recirculating-ball, light and slow off-center compared with European contemporaries but faithful and predictable. With the standard drums, pedal effort is reasonable though fade appears after a few hard stops. The SS’s firmer springs and shocks keep roll in check, though the live rear axle will tramp if provoked on rough surfaces. Big-block cars (Z16 and later SS 396) add welcome torque at the expense of front-end mass; they prefer measured inputs and clean lines. The Z16’s boxed frame and uprated brakes/suspension deliver a notably more planted feel over a base Malibu SS—less cowl shake, more stability as speeds climb.

Ownership Notes: What Enthusiasts Should Know
- Chassis and body: Inspect frame rails near rear control arm mounts, cowl plenum, lower fenders, quarter panels, trunk drop-offs, and windshield bases—common rust sites on A-bodies.
- Powertrains: Small-blocks (283/327) are durable and well-served by the aftermarket. Big-block cooling and fuel delivery must be spot-on; marginal radiators or lean carburetion will show up quickly in hot conditions.
- Driveline: Muncie 4-speeds (M20/M21) are robust; ensure synchro health and correct shifter alignment. Powerglide automatics are famously tough. Z16 and later SS 396 cars use 12-bolt rears; earlier small-block SS cars typically have 10-bolt axles.
- Brakes and suspension: Drum brakes benefit from proper shoe arc-matching and quality linings; front disc conversions on 1964–1966 cars are a well-accepted upgrade, mirroring the 1967 option. HD springs/shocks and good bushings tame axle hop.
- Service cadence: Conventional points ignition likes periodic dwell/timing checks and fresh plugs every few thousand miles. Solid-lifter big-blocks (e.g., 375-hp 396) require periodic valve lash; small-block hydraulic cams are lower-maintenance.
- Parts availability: Excellent for mainstream Malibu and SS 396 components. Z16-specific parts (brakes, frame bits, instrumentation) are scarce and expensive; originality matters enormously on those cars.
- Restoration difficulty: Straightforward body-on-frame construction; panel availability is strong. Correct SS trim, gauges, and date-coded driveline components separate good restorations from great ones.
Cultural Relevance, Media, and Market
The A-body Malibu/SS quickly embedded itself in American car culture. Drag strips across the country saw Malibu SS small-blocks and later SS 396s running in Stock and Super Stock, often with dealer sponsorship. Popular media cemented the image: a 1964 Malibu convertible notably appeared on the silver screen, and the Chevelle/SS lineage became a shorthand for the classic muscle-car archetype.
Collector interest spans a wide spectrum. Well-restored 1964–1965 Malibu SS small-block cars trade in attainable territory relative to their big-block successors, while documented Z16s occupy rarefied air—examples have achieved auction prices well into the six figures. 1966–1967 SS 396s, especially with desirable options or high-output engines, continue to be cornerstone pieces in muscle-car collections.
FAQs
Was the Malibu SS available for the entire 1964–1967 period in the U.S.?
Not exactly. Malibu SS existed in the U.S. for 1964–1965. In 1966 the SS became its own model as the Chevelle SS 396. Canada retained a Malibu SS identity into 1966–1967, typically with small-block power.
What engines did the 1964–1965 Malibu SS offer?
Inline-six options (194/230) and small-block V8s (283 and 327 in various states of tune). The 1965 Z16 Malibu SS 396 was a limited-production big-block outlier that previewed the 1966 SS 396 model.
How quick is a properly tuned Malibu SS?
A 327/300 with a 4-speed is a mid-7-second 0–60 mph car and a mid-15-second quarter-miler. The 1965 Z16 can dip into the mid-14s in the quarter on period tires.
Known problem areas?
Rust in typical A-body zones, worn suspension bushings, weak or out-of-round drums causing pull/fade, marginal cooling on big-blocks if the system isn’t fresh, and tired motor mounts leading to fan-shroud interference. Verify correct SS trim and that the car wasn’t “cloned.”
Are parts easy to source?
Mechanical and body parts are broadly supported. SS-specific interior and exterior trim is widely reproduced, though Z16-only components are difficult and expensive to locate.
Value trends and auction prices?
Documented Z16s have recorded six-figure results at major auctions. Well-restored SS 396s—especially higher-output configurations—command strong money. Small-block Malibu SS cars remain comparatively accessible, with condition, originality, and documentation driving price.
Brakes and handling—what should I expect?
Stock drums are adequate for casual use but will fade; 1967-style front discs resolve that. Handling is predictable with moderate roll; proper shocks, quality tires, and alignment make a big difference without compromising originality.
What’s the difference between Malibu SS and Chevelle SS 396?
Malibu SS (1964–1965 U.S.) was an option package on the Malibu trim and could be paired with sixes or small-block V8s. From 1966, the SS was its own Chevelle model with standard big-block 396 power in the U.S.
