The engine would have ranked the Pontiac GTO as one of the most powerful muscle cars ever to roll off the assembly line, but it was not to be. The manufacturer had originally intended to fit the GTO with the legendary cubic inch Ram Air V engine, complete with tunnel port heads. Narrower grille openings and a slightly reshaped nose completed the front-end redesign, while the distinctive color-matched Endura urethane bumper was retained. The hidden headlight design was ditched in favor of four rounded headlamps set into deep bezels. In keeping with its tendency toward modest mid-generation restylings, the GTO featured a number of aesthetic changes over the previous year. Rated conservatively at horsepower and producing a tremendous pound-feet of torque, the HO gave the GTO the powerful aggression needed to appeal to performance-minded buyers. Beginning at cubic inches inthe limit was increased to cubic inches in InGeneral Motors removed the limit altogether. The GTO was a popular seller at the time and remains a sought-after target for collectors today, and few iterations can match the brawny Pontiac GTO For most of its early run, the venerable A-body platform was subject to a corporate policy limiting the maximum engine size available. An innovative design feature was mounting the rocker arms on ball pivots on studs set into the cylinder head, rather than using a separate rocker shaft.ДЄlong with being cheaper to build, this allowed more consistent valve action with less weight than a conventional shaft.Here is some general information about the vehicle. The up Pontiac V8 was an overhead valve engine with cast iron cylinder heads and block and wedge-shaped combustion chambers. The main innovation of the Pontiac engine was reverse-flow cooling and the stamped rocker-arm system, which had been devised by Pontiac engineer Clayton Leach in At the request of Ed Colegeneral manager of Chevroletthe layout was also used by the Chevrolet V8 released inan exception to the customary GM policy of allowing a division one year of exclusive use of an internally developed advance.ДЇederal emissions standards and the drive towards 'corporate' engines shared among all GM divisions led to the progressive demise of the Pontiac V8 through the late s. Pontiac continued to manufacture its own engines, distinct from BuickCadillacChevroletor Oldsmobileuntil Pontiac engines were used in its U. Pontiac planned to produce the models with the V8, but Buick and Oldsmobile appealed to GM management and earned a 2-year delay.

As a result, it was remarkably free of teething problems. Despite their work, the division's conservative management saw no immediate need to replace the Pontiac Straight When Robert Critchfield took over as general manager inhe launched an ambitious plan to move Pontiac into the upscale, mid-range market occupied by Oldsmobileand that demanded V8 power.ДЄ new engine was fast-tracked, its relatively late start allowing it to take advantage of developments proven in the Oldsmobile V8 and Cadillac V8. The test results showed Pontiac that an L-head engine simply couldn't compete with overhead valve V8 engine designs. The Pontiac V8 engine is a family of overhead valve V8 engines manufactured by the Pontiac Division of General Motors Corporation that made its debut in Pontiac began as a 'companion' to the Oakland division of the General Motors line of automobiles in Pontiac successfully competed against more-expensive inline four-cylinder models with their inline flathead six-cylinder engines.ДЄfter outselling Oakland, Pontiac became the sole survivor of the two by In addition to the inline 6, Pontiac used the Oakland V8 for one year,debuting an inline 8 in The development of this V8 dates back towhen engineers began considering new engine designs for postwar cars.
