Feuling Reaper 508 Cam for Harley Davidson M-Eight Engines SKU #1349
- Produce more power and torque in the riding rpm range, improving throttle response, acceleration and fuel mileage
- Smooth camshaft lobe ramps are easier on valvetrain components and eliminate excessive valvetrain noise and wear
- Dyno proven and track tested
- 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 508 cam with Race Series® oiling system PART #7097
- High-lift valve springs are required; see Feuling Endurance BeeHive valve spring kits PART #s 1107, #1108 or High-Load valve springs PART #1207 (High-Load requires the use of Feuling Race Series® lifters)
- Heavy-duty pushrods are highly recommended; see PART #0928-0091
- 2250 - 6250 rpm range
- Made in the U.S.A.
NOTE: Due to the unstable nature of this 4-valve engine design with one rocker arm activating two valve springs, Feuling highly recommends running one-piece pushrods over quick-install adjustable pushrods to maintain maximum cam/valve lift and reduce valvetrain harmonics and associated hydraulic lifter issues.
NOTE: Feuling fastener kit PART #3047 also highly recommended to help prevent cylinder head cracking; kit replaces the rocker shaft bolts with studs and nuts to help reduce the stress of the rocker shaft standoffs.
