Everything To Know About The Oldsmobile Rocket 88 V8 Engine

The Oldsmobile may no longer be in production, but it's one of the most famous cars ever built by General Motors. Having been defunct for over 20 years, the Oldsmobile has a long legacy and part of that is due to the Rocket 88 V8 engine that powered the vehicle. This engine dates back to 1949, and it was one of the first short-stroke, high compression overhead valve V8s in production — far from the biggest GM engines built. Its small size and performance lent itself well to racing, and it had a torrid two-year run powering numerous NASCAR drivers to victory between 1949 and 1951. It packed all of the power without coming with the extra weight of the Oldsmobile 98 engines.

Years after its production, the engine has taken on a new life as one of the most famous engines built by GM. It's hard to really explain how influential this motor was, but perhaps pop culture can tell the story. The song "Rocket 88" by Ike Turner and Jackie Brenston is often credited as the birth of the rock and roll genre, and it's a song about this Oldsmobile engine. 

The Oldsmobile Rocket 88 is increasingly difficult to track down given the time that has passed. In March 2024, YouTube channel Rugged Wrench showed the engine can still run if you find it in good shape. That's likely the exception to the rule, but it proves some Rocket 88 V8s are still kicking.

Considering one of these can still rev up and get going despite sitting unused for 40 years, it should come as no surprise to see the Oldsmobile 88 V8 engine is durable. The compact, short-strike design created some important benefits at the time; notably, lower piston speeds that led to less friction in the engine. Meanwhile, the overhead cylinders gave additional breathing room and created a better compression ratio. These factors led to a reliable and powerful motor.

It was originally planned for the engine to be dropped into the heavier Oldsmobile 98 models before a shift was made to put them in the 88s, hence the change in name. While this Oldsmobile V8 got its start at 135 horsepower, it eventually grew to 345 horsepower in 1964 before giving way to a second generation. By the end of its production, it was used in both the Oldsmobile 88 and 98 models so it did fulfill its initial purpose, and even some unintended purposes. The Oldsmobile 88s were used to run moonshine thanks to being faster than other cars on the road, while still having ample space for liquor.
