Andrews M520 Cam for 2017-2026 Harley M8

Product Description

Andrews M520 Cam for Harley Milwaukee-Eight

Build more torque and horsepower from a modified Harley-Davidson Milwaukee-Eight with the Andrews M520 Cam. Designed for larger-displacement and higher-output M8 combinations, the M520 provides increased airflow and a broad performance range while keeping the power usable for aggressive street riding.

Andrews designed the M520 for modified engines and larger cubic-inch combinations where the factory cam becomes a restriction. Its .520" intake and exhaust lift, 228°/248° duration at .050" and 40° intake closing point provide increased breathing capability while maintaining a broad powerband of approximately 1,600 to 5,500 RPM. High-lift valve springs are required.
