The Harley-Davidson 88 cubic inch (ci) engine, commonly found in models like the Heritage Softail and Road King, typically produces around 65 to 70 horsepower. The exact horsepower can vary slightly based on the specific model and any modifications made to the engine. Overall, the 88 ci engine is known for its strong torque and reliable performance rather than high horsepower.
The average at the rear tire from a stock 88ci is about 58HP. Add a good free flowing exhaust and intake and it will make about 67HP.

If I'm not mistaken a 2004 Dyna Wideglide has an 88 C.I. motor. Harley does not list or advertise horsepower on any of their engines. I have a 2008 FXSTB Night Train with a 96 C.I. and stock it ran about 63 - 67 HP. So I would imagine a 88 incher would be running about 58 -60 HP.
