Feuling 508 M-Eight Chain Drive Reaper Camshaft for Harley Milwaukee 8 M8 17-25
508 CAM - The Grim Reaper Aggressive pulling power with a nasty sound. This camshaft revs up faster than the 521 grind, sounds nastier and pulls harder but is more difficult to tune. The REAPER 508 grind will shine in 114 and larger cubic inch engines with added compression ratio. Ported cylinder heads are not required but will complement the cam and add even more pulling power throughout the range. The stock throttle body produces an excellent powerband and use of a high flow throttle body will increase peak power numbers. A high flow exhaust system and air cleaner is highly recommended for optimal performance. FEULING recommends matching this cam with our RACE SERIES oiling system.
NOTE: High Lift valve springs are required on stock cylinder heads, see FEULING BEEHIVE valve spring kit #1107 (DRAG# 0926-2973) or #1108 (DRAG# 0926-2974). SE cylinder heads have high lift valvesprings and will accept the 508 and 521 grind cam. Heavy Duty one piece pushrods are also highly recommended see #4087.
