The 1949 Oldsmobile 98 Holiday paired a landmark body style, one of the first hardtop coupes GM ever built, with only 3,006 produced, with an engine that changed the industry outright: the 303-cubic-inch Rocket V-8, the first mass-produced overhead-valve V-8 in America. Together they cut 10-to-60 mph times by 4.6 seconds over the prior year’s car and helped kick off the horsepower race that would define American muscle cars for decades to come.
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.
