rating), HD shocks (valving with 50% more restriction), a 15/16 diameter front and 7/8 diameter rear sway bar, and boxed lower rear control arms with denser bushings. Other standard 442 equipment included Muncie M20, heavy duty clutch with higher rate springs in the pressure plate assembly, HD manual steering ratio 20:1 versus the standard ratio 24:1, performance rear axle ratio 3.36:1, dual exhaust, 14x6 HD wheels sporting 7.5 x14 US Royal 80XP Black with red stripe tire, front fender and rear decklid 442 medallions, and a dual snorkel air cleaner. The 442 was not equipped with power brakes or steering, unless added as an option. The frame, part number 3837595, was not unique or modified for the 442 option, and could be found under F85s equipped with a manual transmission. There was an HD frame option in 1964, part number 9773002; which was boxed, but it was not standard equipment for the 442. Unlike the 1965 442 model built in Lansing, the 1964 442 does not have an option code on the data plate. There is documentation available showing that the 1964 442 was built in both Lansing and Fremont. The package was dubbed 4-4-2 based on its combination of four-barrel carburetor, four-speed manual transmission, and dual exhausts. It was available on any F-85 or Cutlass model except the station wagon, although most were Cutlass hardtop coupés (Oldsmobile archives indicate that approximately 10 four-door sedans were built with the B09 option). A total of 2,999 were sold. Motor Trend tested an early 1964 4-4-2 with a 3:55 rear axle (standard ratio was 3.36:1) and found that the 3,440-lb (1,560 kg) car ran 0–60 mph (0–96 km/h) in 7.5 seconds, the standing quarter mile in 15.5 seconds at , and reached a top speed of 116 mph (185.6 km/h). 1965 With the GTO receiving GM corporate sanction to receive their full-sized car's 389 V-8, Oldsmobile followed suit and replaced the 4-4-2's standard 330 CID with the new 400 CID (6.6 L). The definition of "4-4-2" was then restated as referring to 400 cubic inches, a four-barrel carburetor (a 515 cfm Rochester four-jet), and two exhausts. Output for the big engine rose to and . The standard transmission became a three-speed manual with column shifter, with a floor shifter four-speed and Oldsmobile's two-speed Jetaway automatic transmission as optional. A heavy duty three-speed with Hurst floor shifter was introduced as a mid-year option.
