Cam - 538 Series - Reaper® - Chain Drive
Features
- Revs up fast and pulls hard in engines with big bore cylinders, modified cylinder heads, intake,compression and exhaust
- 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
- Made in the USA
- Cam specs measured in the engine on the lifter @ 0.050 using a 1.61 rocker arm ratio.
