1964 Chevrolet Impala
For 1964, the Impala was restyled to a more rounded, softer look. The signature taillight assembly had an "upside-down U" shaped aluminum trim strip above the taillights, but the individual lights were surrounded by a body-colored panel. The 409-cubic-inch (6.7 L) returned as the big-block option, as well as the 2X4 carburetor setup for the 425 horsepower motors. SS models continued to feature the engine-turned aluminum trim. Rooflines were carried over from 1963 unchanged. Back-up lights were standard.
