Cam - 508 Series - Reaper - Chain Drive - M8

Features

• 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
• 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 - 5900 rpm range
• Made in the USA
• Cam specs measured in the engine on the lifter @ 0.050 using a 1.61 rocker arm ratio.
• 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.
