The 1970 Oldsmobile 442 W-30 remains one of the most sophisticated expressions of the golden muscle car era. This specific convertible, originally delivered to Rhode Island, represents a decades-long journey of preservation and performance. It successfully blends the raw power of the Rocket V8 with the breezy freedom of a power-operated soft top. After undergoing a significant metal and mechanical refurbishment in 2021, the car now shines in vibrant Matador Red. Most notably, a detailed inspection by Cas-Am Performance identifies this vehicle as a genuine high-performance W-30. It stands as a testament to the enduring appeal of Oldsmobile’s ultimate performance package. Collectors will surely appreciate its combination of documented history and classic styling.
Rocket 455 V8 and Muncie Four Speed Performance
The heart of this 1970 Oldsmobile 442 W-30 is a replacement 455ci V8 rebuilt to period-correct standards. This engine features an iconic four-barrel carburetor topped with a functional ram-air induction system for maximum intake efficiency. Specialized W-30 intake manifolds and “KA” cylinder heads ensure the motor produces its legendary mountain of torque. Drivers will enjoy rowing through the gears of the Muncie four-speed manual transmission during spirited weekend drives. A limited-slip rear differential helps put the power to the ground effectively through the rear wheels. Meanwhile, a dual exhaust system with Flowmaster mufflers provides a deep, aggressive tone that fits the car’s personality. This mechanical setup delivers an authentic high-output experience from the muscle era peak.
Exterior Restoration and Matador Red Finish
The exterior transformation of this 1970 Oldsmobile 442 W-30 was completed in 2021 with impressive results. Experts repaired original metal in the frame, floors, and firewall before applying the striking Matador Red paint. Contrasting black stripes on the hood and body sides accentuate the car’s muscular, flowing fender lines. The black power-operated convertible top offers a crisp silhouette when closed and effortless open-air cruising when tucked away. Signature trumpet-style exhaust finishers peek out from beneath the chrome rear bumper for a traditional look. Super Stock I wheels wrapped in white-letter Goodyear Eagle tires provide the perfect period-correct stance. This combination of colors and accessories makes the vehicle a standout on any show field.
Ivory Vinyl Interior and Vintage Appointments
Inside the cabin, the 1970 Oldsmobile 442 W-30 features a bright Ivory vinyl interior that contrasts beautifully with the red paint. Front bucket seats and a rear bench provide comfortable accommodations for four adults during long-distance tours. Woodgrain trim accents the center console and dashboard, adding a touch of upscale class to the sporty cockpit. For audio entertainment, the factory AM radio is joined by a nostalgic under-dash eight-track cassette player. Gauges were recently replaced during the restoration, including a tachometer with an inset clock for precise monitoring. Although minor wear is present on the armrests, the overall presentation remains high for a driven classic. It is a space that perfectly captures the luxury-performance balance of Oldsmobile.
Engine Specifications and Drivetrain Hardware
This 1970 Oldsmobile 442 W-30 draws its massive strength from a 455 cubic inch Rocket V8 engine. It utilizes a Muncie four-speed manual transmission to send power through a limited-slip rear differential for maximum traction. Braking is handled by a power-assisted front disc system paired with traditional rear drums for reliable stopping power. The suspension benefits from power steering, making the large convertible surprisingly easy to maneuver through tight corners. 14-inch Super Stock I wheels ensure the car maintains its original driving characteristics and aesthetic. A dual exhaust system with trumpet finishers ensures the big block breathes freely under heavy load. These specifications highlight a vehicle engineered for both straight-line speed and comfortable touring.
