Oldsmobile W-Powered Muscle Cars: The W-33s
W-33s in 1965 offered a 123-inch wheelbase with their Coke bottle profile bodies and semi-fastback rooflines on the Holiday coupes. These included a new 425 cubic-inch Super Rocket V8 (with ratings of 300-370 hp!). The 3-speed Turbo Hydra-Matic transmission with the torque converter replaced the original Hydra-Matic transmission, which had been previously used by Olds since the onset of the 1940s.) B-body cars, on the other hand, had a 4-speed manual transmission with a Hurst floor shifter.
The standard family version, that introduced itself to the world in 1966, had a bench seat padded with foam and a bucket center arm rest as well as Olds’ Tilt-Away steering column. Not only was the 425 lighter in weight than the 394, it also came in hp versions of 300, 310, 360, and 370 (300 and 310 used two-barrel carburetors while 360 and 370 used four-barrel carburetors).
The 1970 W-33s offered a Delta 88 performance option. This was available in coupe, convertible, or four-door.
With a loaded A/C interior and drop-top appearance, the W-33 was rare due to its incredible features—including a large, 455 cubic-inch V8 beneath the hood.
This V8 engine was made for power, along with its 455 cubic-inch block for the motor. It also had a TH400 three-speed automatic transmission to enable for smoother cruise-ability. In addition, there was power steering, front disc brakes, and modern (at the time, anyhow) Hankook tires.
