Features
  • Produce more power and torque in the riding RPM range, improving throttle response, acceleration and fuel mileage
  • High-lift valve springs are required
  • Heavy-duty pushrods are highly recommended
  • 2250 - 5900 rpm range
  • Made in the USA
  • Cam specs measured in the engine on the lifter @ 0.050 using a 1.61 rocker arm ratio
  • 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
  • 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
