Chevrolet II Nova SS
In 1962 and 1963 the Nova option for the Chevy II was available in a convertible body style, and a two-door hardtop was available from 1962 to 1965, although the hardtop was dropped when the 1964 models were first introduced, but subsequently brought back to the line later in the model year. Like all Chevy two-door hardtops, the body style was marketed as the Sport Coupe.
For 1963, the Chevy II Nova Super Sport was released, under RPO Z03. It featured special emblems, instrument package, wheel covers, side moldings, bucket seats, and floor shifter, and was available only on the 400 series sport coupe and convertible. Cost of the package was US$161.40. As mentioned above, the Nova option could not officially have V8 engines at this time—the standard SS engine was the six-cylinder—but small-block V8 engine swaps were commonplace among enthusiasts.
