Similar specs as the M828B, however this cam shifts the power curve 300-500rpms more towards redline. It is a great option if you have ported your stock heads along with your 128” big bore kit or if you plan on using a larger intake manifold & throttle body over stock sizing.

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 5800-6300rpms. It produces a very distinct idle sound that will give you that “lumpy” rumble that you are looking for out of your upgraded engine!
