Shines in 114" and larger engines with increased compression
Easier to tune, better street performance, and higher RPM range than the 508
NOT A BOLT IN CAM
Requires high lift valve springs
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
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.
