This is the story of an engine. Not just any engine, but the engine that created the idea of "American Muscle".

It was the lightest, most powerful airplane engine in the world during WWI and it was designed by two guys in a hotel room during a five day marathon in Washington D.C.in 1917.

Making 450hp and being produced by multiple American car companies, this engine was a master class in simplicity, integration of existing ideas, and mass production.

While it can't really be said that it solved the war for the allies, what it did do was to introduce the idea of an America that stood as a colossus of industry among its peers in the world.

The Liberty V-12 has an awesome story and the engine itself is worthy of your admiration.
