Oldsmobile reshaped the 1970 Cutlass Supreme around comfort and style rather than raw muscle car numbers — but buried in the order sheet was an option code that turned this luxury coupe into something considerably faster than its badge suggested. Most buyers never checked that box, which is exactly what makes finding one today interesting.
1970 was the year GM finally let Oldsmobile drop its biggest engine into the Cutlass 442, after years of a corporate ban on big-block mid-size cars. The standard 455 made 365 horsepower, but the W-30 option pushed that to 370 horsepower and a sub-15-second quarter mile. See the seven Cutlass body styles offered that year and the Rocket V8 that finally gave the 442 room to breathe.
