1967–1969 Chevrolet Camaro Baldwin-Motion
Historical Context and Development
By 1967, Chevrolet had finally fielded a rival to Ford’s Mustang. The first-generation Camaro was a flexible platform that could be optioned from six-cylinder grocery-getter to tire-vaporizing big-block SS. On Long Island, a partnership between Baldwin Chevrolet (in Baldwin, NY) and Joel Rosen’s Motion Performance crystallized a different idea: sell a new Camaro with the paperwork and warranty of a dealer car, then immediately transform it with proven speed-shop hardware. The result wore SS-427 striping and Motion badging, and it carried a reputation forged at East Coast drag strips and in the pages of period performance magazines.
Unlike factory COPO cars with clandestine central office builds, the Baldwin-Motion formula was out in the open: customers ordered through Baldwin Chevrolet’s showroom, chose their options, and Motion Performance executed upgrades tailored to street/strip use. Packages were tiered, culminating in the Phase III builds—Camaro, Chevelle, Nova, Corvette—engineered to meet an advertised 11.50-second quarter-mile standard on appropriate tires and gearing.
From a corporate vantage, Baldwin-Motion filled a niche the factory could not openly occupy. Chevrolet could sell you an SS396; Baldwin-Motion would sell you the SS-427 Camaro Chevrolet never cataloged, using either the iron-head L72 427 or the aluminum-head L88 427, along with ancillary hardware to make the power stick. In the period muscle-car arms race, the Baldwin-Motion Camaro’s natural competitors were the Yenko and Dana 427 Camaros, Nickey conversions out of Chicago, and later, the COPO 9560/9561 cars—plus factory big-block intermediates and Hemi E-bodies on the drag strip.
Engine and Technical Specifications
The heart of the Baldwin-Motion Camaro was Chevrolet’s Mark IV big-block V8, typically transplanted into an SS or RS/SS donor. Motion Performance matched aggressive camshaft profiles with proper carburetion, ignition, and exhaust, and then dialed suspension and driveline for traction. Signature visual cues included the SS-427 striping and decals, Motion badging, and specialized hoods—early cars often used a Stinger-style scoop; later builds adopted Motion’s distinctive multi-scoop hoods.

Driving Experience and Handling Dynamics
A properly sorted Baldwin-Motion Camaro feels unapologetically mechanical. The big-block’s solid lifters chatter lightly at idle, the clutch is heavy, and the throttle opens a well of torque that can haze bias-ply rear tires through the first two gears. Motion’s Phase III cars typically included traction aids—overload springs or traction bars, sticky rear tires, and appropriate axle ratios (4.10s and 4.56s were common strip choices)—so the car could hook on a prepped surface. Steering is period-quick but not nervous; with the weight of a Mark IV over the front axle, front-end geometry and shock valving matter. Motion tuned shocks and bushings to keep the nose from pogoing on the shift, improving 60-foot times.
On the road, the L72 cars are the friendlier companions—still demanding, but content on premium pump fuel of the day—while L88 builds, with their high compression and big cam timing, were race-bred and far less tolerant of casual use. Gearboxes ranged from Muncie close-ratio 4-speeds (M21/M22 "Rock Crusher") to heavy-duty Turbo-Hydramatic automatics; the latter, paired with a high-stall converter, made for devastatingly consistent quarter-mile passes. Braking typically combined front discs with rear drums; fade resistance was acceptable for the era, but these were drag-strip terrors first and foremost.
Performance Specifications
Performance varied by build sheet, gearing, and tire choice. Motion Performance advertised Phase III Camaros with an 11.50-second quarter-mile guarantee when appropriately equipped. Period tests of Motion-prepared big-block Camaros recorded explosive acceleration in line with that claim.
| Metric | Representative Figure (period/advertised) | Notes |
|---|---|---|
| 0–60 mph | Mid-4s (build and tire dependent) | Documented period tests of Motion Phase III big-block Camaros reported mid-4-second sprints with proper gearing and traction. |
| Quarter-mile | 11.50 sec (Motion guarantee) | Phase III cars were sold with an 11.50-second ET guarantee when configured for the strip. |
| Top speed | Gearing limited; circa 120–140 mph | Tall gears increased v-max; short strip gears capped speed. |
| Curb weight | ~3,400–3,600 lb | Depends on options, big-block equipment, and add-ons. |
| Layout | Front-engine, rear-wheel drive | Rigid rear axle on leaf springs |
| Brakes | Front discs, rear drums | Heavy-duty components specified on many builds |
| Front suspension | Independent, unequal-length A-arms, coil springs | Motion valving/shock tuning for weight transfer |
| Rear suspension | Live axle, multi-leaf springs | Traction aids common on Phase III |
| Gearbox | Muncie 4-speed (M21/M22) or TH400 automatic | Axle ratios frequently 4.10–4.56 for strip setups |

Ownership Notes
- Maintenance cadence: These are solid-lifter big-blocks with period performance tuning. Owners typically perform frequent oil changes using high-zinc formulations and check valve lash at regular intervals. Ignition points, plugs, and carb calibration require periodic attention—especially on L88 builds.
- Fuel and cooling: L88-spec engines demand high-octane fuel and robust cooling. Verify radiator capacity, shrouding, and fan clutch integrity to avoid heat-soak in traffic.
- Driveline durability: With 4.10–4.56 gears and sticky tires, rear axle bearings, u-joints, and clutches see heavy loads. Proper traction aids and pinion angle setup reduce hop and part wear.
- Parts availability: Core first-gen Camaro chassis, trim, and brake parts are widely supported. Period-correct Motion pieces—SS-427 graphics, specific hoods, decals, and dated speed parts—are scarce and valuable; authenticity matters enormously.
- Restoration difficulty: Mechanical restoration is straightforward for a seasoned big-block Chevy specialist. The challenge is documentation and sourcing era-correct hardware (Holley list numbers, period headers, ignition parts). Preserve any original Motion paperwork, window stickers, and dealer invoices.
Cultural Relevance and Market
Baldwin-Motion Camaros were media darlings in the muscle era, appearing in period outlets such as Hi-Performance Cars and Super Stock & Drag Illustrated, often photographed pulling the left front wheel on launch. The Motion Performance name carried weight at East Coast drag strips, and the SS-427 stripe package became an instant calling card on the street.
Collector desirability rests on authenticity and provenance: documented Baldwin Chevrolet paperwork plus Motion invoices/receipts, original components, and period magazine features can dramatically enhance value. At major U.S. auction houses, correctly documented Phase III Camaros routinely command strong six-figure results, with L88-based cars and highly original survivors particularly coveted.
Frequently Asked Questions
How do Baldwin-Motion Camaros differ from Yenko or COPO cars?
Yenko and other dealers (Dana, Nickey) also performed 427 swaps, while COPO cars were central-office factory builds. Baldwin-Motion cars were ordered through Baldwin Chevrolet and upgraded by Motion Performance, often more extensively tuned, and sold with Motion’s performance guarantee.
What engines were commonly used?
The iron-head L72 427 (factory 425 hp) and the aluminum-head L88 427 (factory 430 hp) were the signature swaps for Phase III Camaros. Motion also tuned 396-powered cars with cam, carburetion, ignition, and exhaust upgrades.
What quarter-mile performance did Motion claim?
Phase III cars were advertised with an 11.50-second quarter-mile guarantee when configured with appropriate gearing, tires, and tuning.
Are production numbers known?
Comprehensive, by-variant production totals are not publicly documented. Builds were individualized, and records are reconstructed from surviving paperwork and period coverage.
What are known ownership pain points?
Solid-lifter valvetrain maintenance, fuel octane demands (especially L88), cooling management, traction-induced driveline wear, and ensuring correct carburetor jetting/ignition timing for street use.
What documentation is considered essential?
Baldwin Chevrolet sales documents, Motion Performance invoices, build sheets, period photographs, and any magazine features or road tests tied to the specific car.
How do these cars drive on modern roads?
They’re unapologetically raw: heavy clutch (4-speed), strong idle quality variance by cam, short gearing at highway speeds, and immense torque. Properly set up, they are tractable and brutally quick, with braking and cornering consistent with late-1960s muscle hardware.
Conclusion
The 1967–1969 Chevrolet Camaro Baldwin-Motion sits at the intersection of dealer showroom and speed shop—a first-gen F-body distilled for the quarter-mile and immortalized by its SS-427 identity. As artifacts of the muscle era’s most audacious collaboration, their allure is equal parts paper trail and pavement credentials. Find a documented car, and you’ll have one of the period’s most charismatic—and quickest—street machines.
