Pontiac's new overhead camshaft six cylinder Tempest engine utilizes a neoprene, glass fiber reinforced, timing belt for its camshaft drive. The successful application of this timing belt provides a quiet, reliable drive for the overhead camshaft. This engine incorporates for the first time hydraulically actuated zero valve lash compensation in an overhead camshaft valve mechanism.
In its standard version, the new engine is equipped with a one barrel carburetor and uses regular fuel, while a four barrel premium fuel option is also offered.
Increased engine performance, high rpm potential, economy of operation, good idle characteristics, smoothness and durability at high engine speeds, and exceptional ease of servicing have been achieved.
