S&S 540C/G Cam Chest Kit For Harley Twin Cooled Milwaukee Eight

Big horsepower numbers are the status symbol of a performance engine, but more often than not, the bolstered torque spec is what you really feel when riding it. This is particularly relevant for the heavy touring machines as it’s torque that rockets you onto the highway and it’s definitely torque that lets you effortlessly push a loaded bagger around slower traffic. Produce stump pulling torque down low in the RPM range as well as maintain respectable horsepower numbers.
