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 supplied as a neutral balance damper and comes with three bolt-in counterweights. This allows this one part number to fit four different small block Chrysler engines. The damper without any weight fits internally balanced 1967 and later 318 V8's standard and Magnum, and all internally balanced 273 and 340 engines with forged cranks. One weight is for 340 externally balanced 1972-’73 engines with a cast crank. A different weight is for 360 externally balanced 1993-’97 engines with a cast crank. And the third weight is for 360 externally balanced 1971-’92 engines with a cast crank. Each counterweight is numbered, and the instructions guide you which weight to use for each style of engine.
