  • Very aggressive pull combined with a distinctive tone: the Reaper 521 profile delivers remarkable performance on 114" and larger engines, especially when compression is increased.
  • Although modified/ported heads are not required, their use will showcase the camshaft and broaden the usable power across the entire RPM range.
  • The stock throttle body retains an excellent power band; replacing it with a high-flow throttle body can further increase available peak power.
  • For optimal performance, a high-flow exhaust system and a high-flow air filter are strongly recommended.
  • EU: Even in European specification, the Reaper 521 offers pronounced pulling power and a "mean" tone, ideal for 1.87 L (and larger) engines with raised compression.
  • Recommended RPM range: 2,250 to 6,250 rpm.
  • Made in the USA.
  • The specifications for this camshaft were measured directly on an engine, at the 0.050" lifter with a 1.61 rocker ratio.
  • Feuling recommends pairing the Reaper 521 camshaft with the Race Series oiling system for optimal lubrication and performance.
  • This profile requires the use of high-lift valve springs to operate correctly.
  • Installing reinforced one-piece pushrods is also strongly recommended to ensure reliability and mechanical integrity under load.
