Autoworld 1967 Chevrolet Impala SS 427

When the SS 427 debuted as a 1967 Impala model, the engine was rated at 385 horsepower. It was essentially the same engine as the 390hp version found in the 1967 Corvette. The primary difference was a Holley carburetor in the Corvette, while the Impala used a Quadrajet. The SS 427 engine had a 10.25:1 compression ratio. It produced 460 lb-ft of torque at 3400 rpm, which was more than ample to get these large cars under way quickly.

The 385hp 427 was continued in the 1968 Impala SS 427, as seen here in Wayne Davis’s Matador Red convertible with a white soft top and white guts. The added rarity here is the 4-speed manual transmission. The 15-inch rally wheels and red stripe tires were standard SS 427 equipment.

Besides the base 385hp SS 427 engine, it was also possible to order a 425 horsepower L72 big-block. Torque was the same as the 385hp engine, but compression was 11.0:1. This is a rare engine. Only 568 units found their way into the engine bays of fullsize 1968 Chevys.

SS 427 Impalas are very distinctive and unique. Sales were modest, so finding an Impala SS 427 (especially a convertible) could be a little challenging. The mostly similar, but not quite as unique, Impala SS 396 was produced in far greater numbers, making it a viable alternative that’s still daring and different.
