Aggressive pulling power with a nasty sound, the REAPER 521 grind will shine in Stage 3 or 4 applications with 117 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 optimalperformance.
