The Star F47 Fighter Street/Race Milwaukee-8 Cam is a street/race hybrid camshaft engineered for serious big-inch M8 builds. With .600” lift and an intake closing point of 47° ABDC, the F47 delivers a broad, hard-hitting powerband purpose-built for 131–143 cubic inch engines. Its unique dual-lobe design combines a low-to-mid range intake lobe with a top-end exhaust lobe, extracting maximum power across the full RPM range from street riding to all-out performance. 
 
High performance valve springs and lifter guide upgrades are required. Star M8 Valve Spring Kit (640SK-2) and Star Gold Lifter Guides (M8726LG) are recommended.
