While it may be hard to believe in today's era of corporate engines, each GM division, at least through the mid-70s, had their own unique design. The Olds was also arguably the first of what later became known as the "muscle car." It all started with SV 49, an experimental short-stroke, high-compression V-8. A new 304-cid engine introduced in 1949 as the "Rocket V-8" and the “Rocket Era” begins. With that engine Oldsmobile quickly became the undisputed king of the stock car circuit.

The Sixties was all about horsepower and performance with the introduction of the 394-cid over head valve V-8 that produced 315 horsepower. Followed by the 400-cid V-8s that made there debut in the Cutlass 4-4-2. In 1968 the legendary 455-cid V-8 producing 365 horsepower came to life and is sought after today by Oldsmobile enthusiasts.  Oldsmobile 307 was produced from 1980-1990 and the 350 was produced from 1968 thru 1980. The Oldsmobile 350 is an entirely different engine then the famous Chevy 350.
