Oldsmobile Rocket 88
For the 1949 model year, Oldsmobile presented two important things – the 88 model series and a new 303 CID V8 engine called the Rocket V8. Both proved very influential in Oldsmobile’s history. The 88 model was relatively light and compact. And the Rocket V8 was considered a hot engine with a two-barrel carburetor and 135 HP on tap (via Top Speed).
The combination of light body and powerful engine in the form of the 1949 Oldsmobile 88 was arguably the first muscle car from Detroit. The new model was available as a two and four-door model and the four-door was more popular with the buyers.
