The high performance GTO version of the Pontiac LeMans intermediate had proved an unexpected success midway through the 1964 model year. The 4-4-2 was born out of competition between Pontiac and Oldsmobile divisions of GM. Lansing, Michigan ( Lansing Car Assembly)įramingham, Massachusetts ( Framingham Assembly)ġ964 1964 Oldsmobile 442 2-door hardtop By 1968 badging was shortened to simply "442", but Oldsmobile brochures and internal documents continued to use the "4-4-2" model 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.īecause 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.
It was originally written "4-4-2" (with badging showing hyphens between the numerals), and remained hyphenated throughout Oldsmobile's use of the designation. 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). 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. 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. If you're not more ET/Timeslip oriented the 280 cam can also work with 3.55 gears and a 4spd on the street.The Oldsmobile 4-4-2 (also known as the 442) is a muscle car produced by Oldsmobile between the 19 model years. The 270 being a decent do it all street cam and the 280 a do it all street cam with a sacrifice of streetability= less lower rpm torque and vacuum for more upper rpm power. "In a 350" it's really the first step in cams that shifts the power closer to the upper rpm's. If you have 9.75+ compression (not likely unless you have flat top pistons and the 67-68cc heads) you could go with more cam like the 280 Magnum but even with 202/160 valves it really likes a mild amount of head porting to help it breath. As long as you have around 9.5-9.75 compression then something like the Comp Cams 270 Magnum would work well with those heads, 355 gears and the 4spd.
If you're looking for something as simple as the 350HP cam then I suggest an older design aftermarket cam because they are easier on the valvetrain.
