descriptionProduce 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

The Grim Reaper aggressive pulling power with a nasty sound

This camshaft revs up faster than the 521 grind, sounds nastier and pulls harder, but is more difficult to tune

The Reaper 508 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

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

High-lift valve springs are required

Heavy-duty pushrods are highly recommended

250 - 6250 rpm range

Made in the U.S.A.

Due to the unstable nature of this 4-valve engine design with one rocker arm activating two valve springs,

Feuling highly recommends running one-piece pushrods over quick-install adjustable pushrods to maintain maximum cam/ valve lift and reduce valvetrain harmonics and associated hydraulic lifter issues
