Used 1970 Pontiac GTO for sale in Kenosha, Wisconsin
We have a beautiful Gold hued 1970 Pontiac GTO here in our Milwaukee showroom. This GTO features a Tan interior and is numbers matching. In 1970 the GTO retained the Endura urethane cover around the headlamps and grille. The suspension was upgraded with the addition of a rear anti-roll bar, essentially the same bar as used on the Oldsmobile 442 and Buick Gran Sport. The front anti-roll bar was slightly stiffer. The result was a useful reduction in body lean in turns and a modest reduction of understeer. The base engine was unchanged for 1970, but the low-compression economy engine was deleted and the Ram Air III and Ram Air IV remained available, although the latter was now a special-order option.A new option was Pontiacs 455 HO engine (different from the round-port offerings of the 1971–72 cars), available now that GM had rescinded its earlier ban on intermediates with engines larger than 400. The 455, a long-stroke engine also available in the full-size Pontiac line as well as the Grand Prix, was dubiously rated by Pontiac as only moderately stronger than the base 350 HP 400 CID and less powerful than the 366 hp (273 kW) Ram Air III. The Pontiac brochure indicated the same 455 installed in the Grand Prix model was rated at 370 horsepower (280 kW). The camshafts used in the Ram Air III and the GTO 455 HO were the same. For example, the manual transmission 455 HOs used the same 288/302 duration cam as the Ram Air III. The 455 was rated at 360 hp (270 kW) at 4,300 rpm. Its advantage was torque: 500 lb·ft (678 N·m) at 2,700 rpm. A functional Ram Air scoop was available. Car and Driver tested a heavily optioned 455, with a four-speed transmission and 3.31 axle and recorded a quarter mile time of 15.0 seconds with a trap speed of 96.5 mph (155.3 km/h) . Car Life test car had the Turbo-Hydramatic 455 with a 3.55 rear differential, clocked 14.76 seconds at 95.94 mph (154.40 km/h), with identical 6.6 second 0–60 mph acceleration. Both were about 3 mph (4.8 km/h) slower than a Ram Air III 400 four-speed, although considerably less temperamental: the Ram Air engine idled roughly and was difficult to drive at low speeds. The smaller displacement engine recorded less than 9 mpg US (26 L/100 km; 11 mpg imp) of gasoline, compared to 10 mpg US (24 L/100 km; 12 mpg imp)-11 mpg US (21 L/100 km; 13 mpg imp) for the 455 This vehicle is located in our Milwaukee showroom.
