Feuling Reaper 508 Series Chain Drive Cam


  • The REAPER 508 grind will shine in 114" and larger cubic inch engines with added compression ratio
  • This camshaft revs up faster than the 521 grind, sounds nastier and pulls harder, but is more difficult to tune
  • The stock throttle body produces an excellent power band and use of a high-flow throttle body will increase peak power numbers
  • Ported cylinder heads are not required, but will complement the cam and add even more pulling power throughout the range
  • The Grim Reaper Aggressive pulling power with a nasty sound
  • 2250 6250 rpm range
