Jim designed this cam to work perfectly for big bore 124-128 cubic inch Gen 1 Milwaukee 8 engines. It works well with stock cylinder heads or upgraded cylinder heads. As with all of Jim’s cams, it generates a very flat torque curve across the rev range and makes its peak HP between 5500-6000rpms. It produces a very distinct idle sound that will give you that “lumpy” rumble that you are looking for out of your upgraded engine! This is our “go to” camshaft if you have upgraded your 114” or 117” M8 to 128 cubic inches.
