Oldsmobile 442 history
2 Exhausts. (However, this was not always true to each vehicle due to the options available.) Output for the big engine rose to 345 hp (257 kW) and 440 lb·ft (597 N·m). The standard transmission became a three-speed manual with the four-speed as an option, and Oldsmobile’s two-speed Jetaway automatic transmission was added as an alternative. The ‘65 was the first 442 to use a Hurst shifter, which was included when the HD 3 speed manual transmission was ordered. The heavy duty 3 speed was a mid year introduction and used a floor shifter, unlike the early 3 speed that used a column shifter.
Other touches added to the ‘65 were chrome body side scoops adorned with 442 badging, chambered dual exhaust pipes, chrome single snout air cleaner, and 442 badging on the dash. Late in the year option N98 was added, which were chrome reversed 14 in × 6 in (360 mm × 150 mm) wheels. It also offered standard bucket seats an[d the rare W30 . The standard engine, now dubbed L78 , was rated 350 hp (261 kW)/440 ft·lbf with a single four-barrel carburetor.
The W30 engine added an outside-air induction system (admitting cool air to the carburetors via tubing from the front bumper) and a hotter cam, rated—or, more likely, underrated—the same as the L69. The battery was relocated to the trunk to make room for the air hoses, which prevented the package from being ordered on convertible models. Only 54 W30s were built by the factory, although an additional 97 were produced for dealer installation.
Hurst shifters were now standard equipment with floor-mounted manual transmissions including the optional heavy-duty three-speed, M-20 wide-ratio four-speed or M-21 close-ratio four-speed. The standard transmission was a three-speed manual with column shift and the two-speed Jetaway automatic with switch-pitch torque converter was optional.The standard 350-horsepower 400 engine could be ordered with any of the four transmissions, while only manual transmissions could be ordered with the L69 three two-barrel option.
