1967 Chevy Impala SS396
Smaller cars went faster when fitted with big engines. First it was the Falcon, the Valiant and the Chevy II. Then along came mid-sized muscle like the GTO and SS 396. By the time the Mustang and Camaro made the scene, big muscle cars like the Imapla SS were beginning to fade from popularity.
The SS package started life as a midyear option for the full-sized Chevrolet in 1961. It became a lot more available in '62 and by '63-'64, the Impala SS was a high-performance icon. In '65, the SS played a major role in Chevy's big-car efforts, but by '66 you could sense a change was taking place.
One of the model's spotlight years was 1967, when a revival of sorts took place. The '67 Impala SS 396 was not just a go-to-work car with a hood scoop. It offered gunboat lovers a "no-excuses-sir" big-car alternative to mid-size muscle.
This is not to say that all Impala Super Sports for 1967 were performance cars. Continuing a practice that started with the '62 models, you could get either a Sport Coupe or convertible with SS markings and an incongruous six-cylinder engine. However, Chevy's Mark IV-based big-block V-8s made the SS name mean something real.
The 396-cid/325-hp Turbo-Jet (L35) engine was a good option for starters. It had a 4.094 x 3.76-inch bore and stroke. With its four-barrel Holley carburetor and 10.25:1 compression ratio, the version used in the Impala SS cranked up 325 hp at 4800 rpm and 410 lbs.-ft. of torque at 3200 rpm. The standard transmission used with this engine in the Impala SS was a fully synchronized three-speed manual gearbox. Options included four-on-the-floor, a console-mounted two-speed Powerglide automatic or the three-speed Hydra-Matic.
The Impala was a big car in 1967. It road a 119-inch wheelbase and was 213.2 inches long overall. Tread measurements were 62.5 inches up front and 62.4 inches at the rear. Regular equipment included 8.25 x 15 tires (or 8.15 x 15 tires if the optional disk brakes were ordered). The V-8-powered hardtop listed for $3,003 and weighed 3,615 lbs. The convertible with a base V-8 had a $3,535 list price and weighed in at 3,650 lbs. Nevertheless, these cars could move from 0-to-60 mph in about 8.5 seconds and did the quarter-mile in around 16.3 seconds.
While not a huge sales success, the 1967 Impala SS collected 66,510 orders for the hardtop and 9,545 for the convertible and most were SS 396s. The big Impala SS models returned to extra-cost-option status after 1967.
