Feuling 508 Race Series Cam Chest Kit For Harley Twin Cooled Milwaukee-Eight

These combination kits not only ensure each individual part is designed to work and function together but to do so in total harmony. Feuling camchest kits include all necessary components from top to bottom of the camchest. They take the guess work out of the ordering process and guarantees the engine builder maximum reliability, peak performance and the coolest engine and oil temperatures obtainable. Kits include a Race Series billet 7075 aluminum oil pump which is 50% harder and stronger than the factory pump holding tighter tolerances under temperature, Race Series hydraulic lifters that have a full .200 of total travel designed with a slower bleed down rate to handle heavy valve spring pressures, increase engine RPM before valve float and feature increased roller clearance for steep ramped camshafts and clearance for the Milwaukee Eight front exhaust camshaft lobe flange, and a High Flow billet 7075 aluminum camplate.

508 Cam Info:

508 Cam is also known as The Grim Reaper with 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. RPM range 2,250-5,900
