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 dimensionally the same as the 1969 through 1979 stock damper. To fit this damper on a 1961-'68 engine requires the use of '69 or later timing chain cover, water pump and related accessories. This damper has the stock accessory pulley bolt circle plus a BB Chevy accessory bolt circle.
