Notes: Our damper is identical in fit and function to the original big block high performance 427 FE Ford damper. It is supplied with a matching bolt-on single v-groove accessory pulley which may or may not be required in all applications. This pulley can be removed and using a supplied adapter you can bolt on any multiple groove FE pulley. This damper is classed as an internally balanced damper although the 428 FE is externally balanced. On that engine all of the external weight is on the flexplate or flywheel. The damper is still a neutral balance damper and has no weight attached to it. All other FE engines (except 428) are internally balanced. Our FE Ford dampers are supplied with a universal timing pointer that will fit any FE engine. This pointer is required because our supplied damper is larger in diameter (same as 427) than some FE dampers and the stock pointer will not work on engines that came stock with the smaller diameter damper.
Professional Products Powerforce Dampers are designed to fit a wide range of engine applications. Powerforce Dampers come internally or externally balanced from the manufacturer but allow additional bolt-on counterweights. With this feature, these Dampers provide high flexibility in switching to different applications and that require more or less balance. This allows one Damper to be used on multiple engines. Professional Products gives a major competitive advantage with versatility combined with quality not found with any other company.
