Story
1964 Chevrolet Impala Super Sport
For 1964, the Impala Super Sport became its own series instead of an appearance package added to another Impala. Buyers could order a six-cylinder Sport Coupe, a small-block V8 cruiser, or a 409-powered car. This page keeps those factory configurations together because the engine alone did not define the Super Sport.
Engines for different uses
The range began with the 140-hp 230 six and 195-hp 283 V8. The 327 came in 250- and 300-hp forms. Three 409s sat at the top: 340 hp with a single four-barrel and hydraulic lifters, 400 hp with a single four-barrel and solid lifters, and 425 hp with dual Carter AFBs. The 400- and 425-hp engines required a manual transmission; Powerglide was available with the 340-hp 409.
Super Sport equipment
Every SS used a Sport Coupe or convertible body with front bucket seats, an all-vinyl cabin, Super Sport trim, special wheel covers, and a console when equipped with Powerglide or the four-speed. Six-cylinder and V8 cars carried different VIN-series identities. Those records establish the series and original engine family, but they do not prove a specific 327 or 409 version.
Production context
References report 185,325 Impala Super Sports for 1964. They also report 8,684 409 installations across all full-size Chevrolet passenger cars, not just Super Sports. No reviewed factory table separates the SS total by exact engine and transmission, so this page does not turn the 8,684 figure into a 409 SS count.
What to verify
Start with the VIN series and Fisher tag, then compare the engine pad, casting and date, transmission, axle code, paint, trim, console, body hardware, options, and original paperwork. A real SS can have a six, small-block, or 409. Conversely, a 409, SS badges, bucket seats, or a console can all be installed in another car.
