Performance and Technical information on engines for Harley-Davidson motorcycles.

This is a list of verified horsepower figures for a variety of Big Twin Evolution Engines. The list provides information on the maximum horsepower recorded, the type of engine cases, the engine displacement in cubic inches (CID), type of cylinder heads with who did the modifications, type of camshaft, type of carburetor, type exhaust system, owner of the bike, the type of frame the engine was mounted in and the source of the data. Data sources used in building this list include Cycle-Rama, AMI, and various magazines. All horsepower figures listed here were confirmed on a dynamometer.
