The Oldsmobile 4-4-2 (also known as the 442) is a muscle car produced by Oldsmobile between the 1964 and 1987 model years. Introduced as an option package for US-sold F-85 and Cutlass models, it became a model in its own right from 1968 to 1971, spawned the Hurst/Olds in 1968, then reverted to an option through the mid-1970s. The name was revived in the 1980s on the rear-wheel drive Cutlass Supreme and early 1990s as an option package for the new front-wheel drive Cutlass Calais. The "4-4-2" name (pronounced "Four-four-two") derives from the original car's four-barrel carburetor, four-speed manual transmission, and dual exhausts (Some maintain that the '2' indicated a limited-slip differential). It was originally written "4-4-2" (with badging showing hyphens between the numerals), and remained hyphenated throughout Oldsmobile's use of the designation. Beginning in 1965, the 4-4-2s standard transmission was a three-speed manual along with an optional two-speed automatic and four-speed manual, but were still badged as "4-4-2"s. Because of this change, from 1965 on, according to Oldsmobile brochures and advertisements, the 4-4-2 designation referred to the 400 cubic inch engine, four-barrel carburetor, and dual exhausts. By 1968 badging was shortened to simply "442", but Oldsmobile brochures and internal documents continued to use the "4-4-2" model designation. First generation 1964 The 4-4-2 was born out of competition between Pontiac and Oldsmobile divisions of GM. The high performance GTO version of the Pontiac LeMans intermediate had proved an unexpected success midway through the 1964 model year. Oldsmobile's hasty response was to beef up their own popular Cutlass, a task given to a team led by performance enthusiast and Olds engineer John Beltz (later responsible for the distinctive and powerful Toronado), aided by Dale Smith and division chief engineer Bob Dorshimer. Contrasted with the 1964 Tempest LeMans GTO with its 389 cubic inch V-8 (introduced in September, 1963 as an option package), the Oldsmobile offering was a conservative package. Technically the "B09 Police Apprehender Pursuit" option, the 442 used the four-barrel carbureted 330 CID (5.4 L) V8, known as L79, but with shorter valve spring retainers, longer pushrods, M400 rod and main bearings, and high lift camshaft, raising rated (SAE gross) output to 310 hp (231.3 kW) at 5,200 rpm. Torque remained , although the torque peak rose from 2800 rpm to 3600 rpm. Enhanced handling was credited to the heavy duty (HD) suspension package that included HD springs (30% higher
