From GM press: The Beach Boys sang harmonies to Chevy’s 409-cid big-block V-8, rated at a thumping 425-hp for 1963. The hardtop ’63 Impala Sport Coupe, with its convertible-look roofline, crisply tailored flanks, and pointed fenders, beautifully showcased the big brute of an engine. The sleek 1963 Impala could also be had with a Chevy 283 or 327 small-block V-8 engine, and was even available as a six-cylinder model. The popular Super Sport package included special SS exterior details and front bucket seats with a console. Collectors drool over ’63 Impalas today – especially when there is an original 409 V-8 under hood – and the ’63 is also a favorite with hot rodders and customizers.
