New hot-rod parts from S&S for Milwaukee Eight engine

Harley-Davidson’s Milwaukee Eight engine might be the latest and greatest the company has to offer, but S&S is still offering you the chance to up its performance.

Whether you’ve got the 114 or 117 version of the Milwaukee Eight, S&S has developed new valve train parts to fit in. The bits range from cams to increase horsepower (the 375, 475 and 550 cams) as well as a cam with stock grind that is designed to work in conjunction with a gear drive to eliminate the cam chain and its tensioner (presumably for reliability reasons). The 375, 475 and 550 cams can also be ordered in a version that uses a gear drive, eliminating the cam chain.

Of course, dropping in the camshaft alone will not make massive horsepower gains; to truly take advantage of the new parts’ advantages, you must add in free-flowing exhaust and intake, as well as other top end parts (stronger springs, new pushrods, new tappets). It’s like the sign from Mad Max: “Speed’s just a matter of money—how fast can you go?”
