When introduced, the 1964 package featured the B09 police option, which included a 290 hp 330ci V8 and heavy-duty suspension with rear stabilizer bar. The 4-4-2 name referred to the package’s four-barrel carburetor, the four-speed manual transmission, and dual exhaust. Oldsmobile added an automatic transmission option in 1965 to expand the 4-4-2 line. But by 1966, it was clear that GM had to offer even more, and offered a 400ci power plant with either the L78 package with four-barrel Rochester carburetor rated at 350 hp, or the TriPower L69 package with triple two- barrel Rochesters that delivered 360 hp, the first time that Oldsmobile had offered a tri-carb option since the late ’50’s (which was promptly dropped by GM again after the ’66 model year). The standard manual three-speed transmission could be improved upon with a console-mounted automatic or four-speed manual Hurst close-ratio shifter. 1966 was also the first year for the W-30 option, which featured a forced-air system which fed directly into the oversized air cleaner and 3 - 2 barrel carburetor set-up from scoops mounted in cut-outs on the lower front bumper. The stock Cutlass suspension was upgraded when front and rear sway bars were added, earning raves for the 4-4-2’s excellent handling.
