Pontiac

The Pontiac Division of General Motors manufactured their own and unique V8 engines from 1955 until 1981 which was much different from Oldsmobile, Chevrolet, Cadillac and Buick. The displacement started at the 287 in cube which had grown as large as the 455 in cube by the year 1970. The engines of Pontiac were largely used by the US car markets and apart from this the Canadians who built Pontiac automobiles had generally used Chevrolet engines. The V8 Pontiac engines were largely used in the GMC pick-up trucks from 1955 until 1959.

The Pontiac Design

The Pontiac V8 engine is basically an overhead valve engine that includes wedge combustion chambers. This engine used a cat iron block and cast iron cylinder heads. The most innovative design feature, however, was with the mounting of the rocker arms on the ball pivots on studs set of the cylinder head which is used more often as a separate rocker shaft. These unique features allowed for more reliable valve action although with less weight than the traditional shaft. All of the V8 Pontiac engines except the 301, 265 and 303 Ram Air V engine have used the 6.625 in connecting rods.

All of the Pontiac V8 engines that were designed from 1955 until 1959 reserved the cooled through a process called the gusher cooling system. The engines were also plagued with corrosion issues which were later removed from their engine designs and were not included in any of the models after 1960. Most of the iterations had an average length that measured 28.25 inches from the edge of the water pump pulley and had an average width of 27 inches and a height of nearly 31 inches excluding the air cleaner. The dry weight ranged from nearly 590 lbs to about 650 lbs which depended on the displacement of the particular year. Most of the Pontiac engines were usually painted light blue in colour. The 389 version of the V8 Pontiac engine was called the Trophy or Tempest V8 engine according to the hp rating and the year. The company was also among the few manufacturers in US that did not usually identify its engine sizes and names with the valve cover decals and air cleaner.

The V8 engine was launched as the Strato Streak model in the year 1955. However it was not long before the model was introduced that the company's management had decided to include the V8 engines in its entire line of models.
