- The Reaper® 538 grind will shine in 124” and larger cubic inch engines with added compression ratio
- The stock throttle body produces an excellent powerband and use of a high-flow throttle body will increase peak power numbers
- Ported cylinder heads are not required, but will complement the cam and add even more pulling power throughout the range
- A high-flow exhaust system and air cleaner is highly recommended for optimal performance
- 2250 - 6250 rpm range
