1968 Pontiac GTO Hardtop Coupe 1968 Pontiac GTO hood-mounted tachometer. General Motors redesigned its A-body line for 1968, with more curvaceous, semi-fastback styling, which was a revival of a streamlining on all GM products from 1942 until 1950 as demonstrated on the Pontiac Streamliner. The wheelbase was shortened to 112.0 in (2,845 mm) on ...

The designation 2+2 was borrowed from European sports car terminology, for a seating arrangement of two in front plus two in the rear. It was designated officially at Pontiac as a "regular performance" model, [2] a thoroughly confusing designation for a vehicle that was clearly intended to be to the Catalina platform what the GTO was to the A-body Lemans: the standard drivetrain was a 2-barrel ...
The 1968 Ram Air II remained at 400 cu. in., again available only in the GTO and Firebird. It was factory rated at 366 hp at 5,400 rpm and 445 lbs.ft. of torque at 3,800 rpm in the GTO, and 340 HORSEPOWER at 5,300 rpm and 430-lb.ft. of torque at 3,600 rpm in the Firebird, with only a small throttle restrictor tab on the Firebird being different.
The GTO was offered as a separate model line beginning in 1966. The Tempest name was retired after 1970, replaced by the T-37 as the base model, which in turn gave way to the LeMans name in 1972. In Canada from 1987 to 1991, Pontiac marketed a rebadged version of the compact L-body Chevrolet Corsica under the revived Tempest name.
The GTO was dropped in 1975, along with the Pontiac 350. The Ventura could be optioned with the Buick 350 V8 instead.

Also for the 1968 model, the 326 cu in (5.3 L) engine was replaced by the Pontiac 350 cu in (5.7 L) V8, which actually displaced 354 cu in (5.8 L), and produced 265 hp (198 kW) with a two-barrel carburetor. An HO version of the 350 cu in (5.7 L) with a revised cam was also offered to start in that year, which developed 320 hp (239 kW).
Also called the GM small corporate pattern and the S10 pattern. This pattern has a distinctive odd-sided hexagonal shape. Rear wheel drive applications have the starter mounted on the right side of the block (when viewed from the flywheel) and on the opposite side of the block compared to front wheel drive installations.
