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.  

Today with the vast array of performance parts available we can turn your Oldsmobile from a mild 300 horse power grocery getter to a wild tire smoking 475 horse power animal.

If you are restoring your early Oldsmobile we can upgrade the horse power and still keep it looking original. Please call us for details.
