Produce more power and torque in the riding rpm range,
improving throttle response, acceleration and fuel mileage
Smooth camshaft lobe ramps are easier on valvetrain components and eliminate excessive valvetrain noise and wear
Dyno proven and track tested
Aggressive camshaft with a nasty sound
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
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 optimal performance
Feuling recommends matching this cam with Race Series oiling system
High lift valve springs are required on stock cylinder heads
SE cylinder heads have high lift valve springs, but will need to be verified
Heavy-duty one piece pushrods are also highly recommended
2250-6250 rpm range
