Powerforce BB Ford Dampers

Professional Products produces two different big block Ford dampers. One suits the 429/460 engine and the other is for all the various FE dampers. 429/460: The 429 and 460 damper utilizes a separate counterweight that is a spacer that goes over the crank and behind the damper. These weights are available from your Ford dealer (#M-6359-D460) and must be used unless the engine assembly has been converted to an internally balanced engine by incorporating heavy metal in the crankshaft. These engines have used different timing pointer locations. Looking at the front, most of these engines have a timing pointer in the "10 o'clock" position. Using the 1/4" keyway in our damper correctly positions the damper on a production crank (or aftermarket crank machined to stock specs) so a "10 o'clock" pointer lines up with the damper TDC mark. Use the 3/16" keyway with Ford Racing cranks #M63030-A600 and B600 to again align a "10 o'clock" pointer to the damper's TDC mark. 

FE: Our FE damper is identical in fit and function to the original big block high performance 427 FE Ford damper. Our damper 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 the supplied aluminum adapter you can bolt on any stock 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.
