Product Details
Highlights
- 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; use of a high-flow throttle body may increase peak power numbers.
- A high-flow exhaust system and air cleaner is highly recommended for optimal performance.
- Rpm range 2250-6250.
- Made in the USA.
- Cam specs measured in the engine on the lifter @ 0.050 using a 1.61 rocker arm ratio.
- Feuling recommends matching 521 cam with Race Series oiling system.
- Requires high lift springs on Gen 1 engines.
- Heavy-duty one-piece pushrods are also highly recommended.
- Not for '23-'26 models with VVT motors.
