The Powerforce line of balancers are intended for non-SFI high performance applications. Although primarily meant for street use, these balancers are also suitable for racing applications where there is no requirement to meet SFI specifications.
It is not recommended to use these balancers in excess of 6,500RPM. Also, they are not recommended for marine or circle track applications due to excessive heat generated. While high temp elastomer is used in every balancer, certain applications are not suitable.
This damper is identical dimensionally to the damper originally used on the high performance 427. That engine's stock damper had an integral single groove pulley. Our damper includes this pulley and although our damper is 7.5" in diameter, it can be used on any FE engine including those that had a stock 7" damper. This damper is designed to allow the removal of the stock single groove pulley, and your multiple groove pulleys can bolt directly to it. An adapter spacer is included with the damper to allow proper belt alignment. This damper also comes with a universal timing pointer to suit the larger 7.5" diameter damper and the pointer will bolt to either of the two different bolt patterns Ford used for timing pointers.
