* 590 Cam was designed as an all out Horsepower Cam for 124ci & larger engines - Big lift lets your big mill breathe high into the RPM range!
* The M8 engine platform is capable of making massive power! It happily accepts big bore kits, stroker cranks and of course high lift cams. The latest from the S&S development team is a 590 that’s designed specifically for use with monster bores, ported heads, high RPMs and making maximum horsepower! Not recommended for stock bore engines.
