Feuling Race Series 521 Camchest Kit


Feuling's bulletproof complete camchest kit includes all necessary components of the camchest, from top to bottom, in one convenient package. In this way, each individual part is designed to work and function together in total harmony. It takes the guess work out of the ordering process, and provides you with maximum reliability, peak performance and the coolest engine and oil temperatures obtainable.

  • Quieter and smoother engine operation
  • Increase oil pressure, scavenge volume and engine oil flow
  • More pressure gear volume over stock
  • More scavenge gear volume over stock
  • More scavenge volume with port sizing, matched passages and holes to the engine case
  • More oil volume to the crankshaft and connecting rod bearing
  • 15-25 degree cooler engine temperatures
  • 15-30 degree cooler oil temperatures
  • 10-30 more PSI of oil pressure
  • Reduces wet sumping, blow by and oily air cleaners
  • Magnets in oil pump to help protect gears and pressure relief valve

521 cam:

  • Aggressive pulling power with a nasty sound, the Reaper 521 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
  • 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
  • High lift valve springs are required
    • Use Feuling Beehive valve spring kit #1107 and #1108

  • Race Series oiling system
  • Billet 7075 oil pump
  • Race Series lifters
  • High flow 7075 aluminum camplate
  • Billet 7075 aluminum oil pump which is 50% harder and stronger than the factory pump holding tighter tolerances under temperature, deeper scavenge kidneys over HP+ oil pump
  • Deeper scavenge kidney ports over the HP+ series for even more scavenge flow volume
  • Race Series hydraulic lifters have a full .200 of total travel designed with a slower bleed down rate to handle heavy valve spring pressures
  • Increase engine RPM before valve float and feature increased roller clearance for steep ramped camshafts and clearance for the Milwaukee Eight front exhaust camshaft lobe flange
