Bolt-in big power for your Gen 2 M8 with the S&S Cycle HPT542 cam. It starts with that idle M8 owners want, the sound of something ready to perform and when you open the throttle you feel it. A mile-wide torque band and high rpm hoprsepower, the HPT542 is what Gen 2 owners have been asking for. With .542" lift it pulls from 2000-6200 rpm. Don't have a Gen 2 but want this cam? Just use S&S Cycle .605" lift springs and you are set. Like all S&S cams, the HPT542 is designed, tested and manufactured in house in Viola, Wisconsin.
