The EMD 567 is a line of diesel engines built by General Motors' Electro-Motive Division. This engine, which succeeded Winton's 201-A, was used in EMD's locomotives from 1938 until its replacement in 1966 by the EMD 645. It had a bore of eight and one-half inches (216 mm), a stroke of ten inches (254 mm) and a displacement of 567 cubic inches (9.29 liters) per cylinder. Like the 201-A and the EMD 645, the EMD 567 was a two-stroke cycle engine. It is a V engine with an angle of 45 degrees between cylinder banks. 567AC engines (an 'A' block which was upgraded to 'C' block specifications) and 567BC engines (a 'B' block which was upgraded to 'C' block specifications) may be upgraded to use 645 power assemblies, theoretically achieving an increase in horsepower, however this upgrade is usually performed to convert a turbocharged engine into a normally-aspirated engine, thereby achieving a reduction in operating cost with no reduction in horsepower. As 645 power assemblies are more readily available than 567 power assemblies, this upgrade may also be employed in so-called 'life extension' programs.
