The 442

1970 saw the lifting of GM's ban on engines greater than 400 cid installed in midsize cars. Although Oldsmobile had gotten around that rule in 1968 and 1969 through the Hurst/Olds, this now enabled Oldsmobile to offer its 455 cid V8 in all 4-4-2s. The Hurst/Olds was dropped from the lineup and wouldn't reappear until 1972. The W-30 hit its performance peak and included a balanced and blueprinted 455 V8 with a hotter cam, performance carb, low-restriction exhausts and the Force Air induction system which utilized two prominent scoops on the hood. The W-30 package also included a lightweight fiberglass hood, plastic inner fenders, aluminum diferential carrier and cover, and less sound insulation in an attempt to cut weight and improve performance. The W-30 option was offered only on Cutlass models, but a new option, the Rallye 350, was offered. Powered by a 350 cid engine, the smallest displacement Oldsmobile muscle car sported the most outrageous exterior, which was only painted in a very bright yellow. Even the bumpers and wheels were painted yellow. a bad mutha-shut yo mouth, that 455 put down 365 horses and 500 pounds of torque tell me about power lol
