Bolt-in power for your Gen 2 M8 with the S&S Cycle HPT542 cam.
Designed to deliver the idle M8 owners want, with a strong sound at idle and a noticeable pull when you roll on the throttle.
Its wide torque band and high-rpm horsepower help it pull from 2000-6200 rpm, and .542" lift gives it the performance range Gen 2 owners have been asking for.
Gen 1 engines require hi-lift valve springs.
