Rb Wedge Dyno Magnum Solid Street Rollers
|
We installed the Comp Cams .575-lift Magnum solid street roller straight up before installing the lifters, pushrods, and rockers. Roller cams usually require stiffer valve-springs, a bronze gear for the intermediate shaft, and a cam button. Comp recommends its 929 springs, which we utilized on both cams tested.
