PRODUCT DETAILS : 
FEULING® camshaft kits for Milwaukee Eight engines include camshaft, lifters and a cam installation kit that includes cam bearing, cam/crank hardware and a gasket/O-ring kit that allows for install of the factory one piece pushrods and or Feuling's recommended heavy duty HP+® 0.165" wall one piece pushrods - Dennis Kirk Part No. # 1401311.

Fastener kit Part No. 275638 is also highly recommend to help prevent cylinder head cracking, this kit replaces the rocker shaft bolts with studs and nuts to help reduce the stress on the rocker shaft standoffs.

521 CAM - Aggressive pulling power with a nasty sound, the REAPER 521 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. FEULING recommends matching this cam with the RACE SERIES oiling system Part No. 1401320. High lift valve springs are required, see BEEHIVE valve spring kit Part No.'s 189642 and 189643. Heavy duty pushrods are highly recommended; order Part No. 1401311.

*Cam specs measured on the lifter @ 0.050" lift with 1.61 rocker arm ratio.  Include camshafts, lifters and a cam installation kit that includes the cam bearing, cam/crank hardware

• Kit also includes gasket/O-ring kit that allows installation of Feuling Heavy-Duty HP+ .0165" wall one-piece pushrods or factory one-piece pushrods
• Race Series® kit includes Race Series® lifters

NOTE: 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.
