The 1970 Chevrolet Chevelle SS Convertible stands as one of the most coveted symbols of the American muscle car era. This specific example is exceptionally rare, being one of only 889 SS 396 convertibles produced for the 1970 model year. It has undergone a professional restoration that returns it to a show-quality standard, preserving the aggressive character that made the Chevelle a dominant force on the street. As it prepares to cross the block at Glendale 2026, it offers a blend of big-block authority and open-air freedom that few vintage vehicles can match.
Aggressive Blue Silhouette and Professional Detailing
The exterior of this Chevelle SS is finished in a striking blue, emphasizing the muscular contours and wide stance characteristic of the 1970 redesign. Every detail has been meticulously attended to, from the professionally show-waxed paint to the correct tower clamps used in the engine bay. The power-operated convertible top provides a sleek profile when up and a classic cruiser aesthetic when retracted. To ensure total authenticity, the trunk compartment is fully detailed with the correct mat, spare tire, and jack, reflecting the high caliber of its restoration.
Refreshed White Cabin with Added Climate Comfort
Inside, the cabin features a bright white interior that provides a sharp contrast to the deep blue exterior. The space has been refreshed with new components, including door panels and high-quality carpets that maintain the factory-correct look. Drivers interact with an original SS steering wheel and benefit from the optional N40 power steering system. A significant enhancement to this build is the addition of air conditioning, integrated at a cost of $6,500, ensuring this classic remains a comfortable choice for long summer drives without sacrificing its vintage charm.
Matching-Numbers L34 Big Block and 12-Bolt Power
The mechanical heart of this machine is the matching-numbers Chevrolet L34 396 V-8 engine. This power unit produces a factory-rated 350 hp/355 PS and is paired with a matching-numbers M40 three-speed automatic transmission. Power is sent to the pavement through a heavy-duty 12-bolt Positraction rear end equipped with 3.31 gears. The car is further enhanced by the optional F41 heavy-duty suspension, which provides a more composed ride. Braking is handled by J50 vacuum power brakes and JL2 power front discs for reliable stopping power.

Elite Rarity in the Muscle Car Landscape
In the current collector market, the 1970 Chevelle SS is often considered the peak of the model’s evolution. While the hardtop variants are highly sought after, the convertible is a significantly rarer find, especially when verified as one of the 889 units produced with the 396 engine.

Its status as a genuine SS convertible with matching-numbers components ensures it will remain a cornerstone of any high-tier collection.

It captures the essence of 1970s performance while offering the modern refinement of a professional restoration and added climate control. For the collector seeking an authentic big-block experience with the added prestige of low production numbers, this blue-on-white convertible is a standout offering. It remains a powerful tribute to the era when Chevrolet ruled the American road with big-block displacement and iconic design.
