The 521 Cam delivers aggressive pulling power and a hard-edged exhaust note. The Reaper 521 grind is best suited for 114 cubic inch and larger engines with added compression. Ported cylinder heads are not required but they complement the cam and add stronger pulling power across the range. The stock throttle body provides an excellent powerband while a high flow throttle body can raise peak power. A high flow exhaust system and air cleaner are highly recommended for best performance. Feuling recommends pairing it with the Race Series oiling system.
Note: VVT Models: Requires FEULING camshaft sprocket #1095 (HD #25400103), HD timing cup #18400117, Feuling sprocket retention kit #3042 and Feuling camshaft spacers #8041. Must also be able to turn VVT feature off in ECM.
