In mid-1956, Pontiac introduced a higher-powered version of its V8. Among other things, this version of the engine was equipped with a high-performance racing camshaft and dual 4-barrel carburetors. This was the first in a series of NASCAR-ready pre- Super-Duty V8 engines and introduced the long line of multi-carburetor equipped engines that saw Pontiac become a major player during the muscle car and pony car era of the 1960s. The enlarged 1956 Pontiac V8 found its way into light-duty GMC pickup trucks.
