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
