The Offenhauser engine was known as the “Offy”. It was an overhead cam monoblock 4-stroke engine developed by Fred Offenhauser and Harry Arminius Miller and originally sold as a marine engine.
In 1930 a race car with a four-cylinder 151 cu. in Miller engine set a new international land speed record of 144.895 mph.
In 1946, the name Offenhauser and engine designs were sold to Louis Meyer and Dale Drake. After this, the engine dominated the Indianapolis 500 and midget racing in the U. S.
