The 1972 model year marked the end of the Chevelle’s most iconic body style and the last year for the big-block SS engine option. Consequently, the 1972 Chevrolet Chevelle SS Convertible is highly prized by collectors today. This stunning example represents one of the most desirable factory configurations available. It is a genuine factory LS5 car, equipped with the formidable 454 cubic inch V8 engine and a rare 4-speed manual transmission. A comprehensive frame-off restoration has returned this classic to its original, brilliant Orange Flame Poly finish, confirmed by a copy of the build sheet.
The Highly Prized LS5 Engine and Drivetrain
At the core of this convertible is the mighty 454 CI V8 engine, identified by the factory LS5 code. This big-block was the pinnacle of performance offered in the Chevelle lineup for 1972. Critically, this engine is paired with its matching numbers M22 Rock Crusher 4-speed manual transmission. The M22 is legendary for its straight-cut gears, which produce a distinct whine and ensure maximum durability under hard driving. This engine-transmission pairing is exceedingly rare in the drop-top SS.
Handling and Stopping Power Upgrades
To match the big-block’s muscle, this 1972 Chevrolet Chevelle SS Convertible was fitted with essential performance components. It features the F41 heavy-duty suspension package, providing improved stability and cornering capability. Stopping power is managed by JL2 front disc brakes, an important safety and performance upgrade from the standard drums. Traction is enhanced by a G80 Positraction differential, ensuring power is delivered efficiently to both rear wheels. The car also features power steering and power brakes, making this powerful machine easier to manage.
Exterior Brilliance and SS Details
Finished in its original Orange Flame Poly, the exterior of this convertible is immediately eye-catching. The color perfectly encapsulates the vibrancy of the muscle car era. The entire car has benefited from a frame-off restoration, guaranteeing the highest quality finish and attention to detail. The SS trim package adds unique styling cues, including the signature blacked-out grille, hood pins, and appropriate SS badging. Completing the classic muscle car look are Argent 5-spoke wheels, wrapped in Firestone Wide Oval tires.
Interior Comforts and Features
The bold exterior color contrasts beautifully with the white interior, creating a period-correct, high-impact aesthetic. The cabin features bucket seats separated by a factory console. This layout enhances the sporty, driver-focused feel of the SS package. For convenience, the car is equipped with a pushbutton radio and a power-operated convertible top. This simple feature makes the transformation from coupe to open-air cruising nearly instantaneous. The overall interior presentation is clean, accurate, and comfortable for any enthusiast.
Engine Specifications and Performance
The 454 CI LS5 V8 engine in the 1972 Chevrolet Chevelle SS Convertible provides serious thrust, despite the change to net power ratings that year.

This torque figure ensures immediate, powerful acceleration off the line and excellent responsiveness at speed. The matching-numbers M22 Rock Crusher 4-speed manual transmission allows the driver to fully exploit the big-block’s powerband. This combination is designed for exciting, high-performance driving.

The inclusion of a copy of the original build sheet provides undeniable documentation of this car’s factory-correct options and provenance. This confirms its status as a highly sought-after factory LS5, 4-speed manual convertible. The rarity of this combination, coupled with a full frame-off restoration, places this Chevelle at the top of the collector market. The 1972 Chevrolet Chevelle SS Convertible is one of the last, best examples of open-air big-block muscle, representing the end of a golden era.
