As mentioned above, the Nova option could not officially have V8 engines at this time—the standard SS engine was the six-cylinder (this was also applicable to the Impala (and later the early Chevelle c. 1964–65) when the SS was a sport and appearance package)—but small-block V8 engine swaps were commonplace among enthusiasts. For 1964, sales were hit hard by the introduction of the new Chevelle, and the Chevy II received its first factory V8 option, a , as well as a straight six. The six-cylinder was all-new, replacing the older Stovebolt engine. Rival manufacturer Chrysler had earlier developed the Slant Six in their Plymouth Valiant, a Chevy II competitor, when the cars were introduced to the public in late 1959 as 1960 models. At introduction in the fall, the hardtop coupe was missing in the lineup, contributing to a loss of sales (as well as showroom appeal). Chevrolet subsequently reintroduced the Sport Coupe in the lineup later in the model year, and it remained available through 1967. The 1965 Chevrolet Chevy II and Nova were updated with cleaner front-end styling courtesy of a fresh full-width grille with new integrated headlight bezels. Parking lights moved down to the deep-section bumper, and sedans gained a new roofline. Taillight and backup lights were restyled, as was the rear cove. The 1965 Chevy II came in entry-level 100 form or as the posher Nova 400, each in three body styles. The Nova Super Sport came as a Sport Coupe only, and its production dipped to just 9,100 cars. Super Sports had a new brushed-chrome console with floor-mounted four-speed manual transmission or Powerglide automatic, but a column-mounted three-speed manual remained standard. Bucket seats wore textured vinyl trim, and the dashboard held ammeter, oil pressure, and temperature gauges. An expanded engine lineup gave customers six power choices of the six-cylinder or V-8 engines; the four-cylinder was available only in the 100. But, for Chevy II enthusiasts, 1965 is best remembered as the year the Chevy II became a muscle car. A V8 was available with up to , suddenly putting Nova SS performance practically on a par with the GTO, 4-4-2, and 271 bhp Mustang 289s-at least in straight-line acceleration. Midyear also brought a more potent 283 with dual exhausts and 220 horsepower. The Chevelle Malibu SS continued to eat away at the Nova SS market: Out of 122,800 Chevy IIs
