Oldsmobile 455 ci Crate Engine

In 1968 the legendary Oldsmobile 455 ci V-8, producing 365 horsepower came to life and is sought after today by many Oldsmobile enthusiasts. Today, with the vast array of performance parts available we can turn your Oldsmobile from a mild 300 horsepower grocery getter to a wild tire smoking 475 horsepower animal.

Our 455 ci crate motor begins with a 455 2-bolt main block and a cast iron precision ground micro polished crankshaft. With the use of a set of Edelbrock Performer RPM aluminum cylinder heads our 455 ci crate motor will pump out 475 horsepower! With that kind of horsepower your Oldmobile is certain to get the respect it deserves!

From custom painted engine blocks to our exclusive March Performance serpentine belt system, Proformance Unlimited can supply you with the crate engine that you have dreamed of and others fear! With over 50 years of shop experience, you can rest assured that we are here to help design and build the engine combination that best suits your vehicles needs.
