Jim designed this cam to bolt in directly to Gen 2 “Center-Cooled” Milwaukee 8 121 cubic inch non-VVT engines. It works with factory valve springs. As with all of Jim’s cams, it generates a very flat torque curve across the rev range and makes its peak HP between 5500-6500rpms. It produces a very distinct idle sound that will give you that slightly “lumpy” rumble that you are looking for! This camshaft was designed specifically for the 121” CVO ST engine but it will also work in big bore 124-131 cubic inch Gen 1 M8 & Gen 2 M8 combos.
