SECTION 6 See OLDBOOK For Early Model Applications All part numbers in BLUE are new for 2024. 581 592 CAM •Get serious with bore size, ported cylinder heads and throttle body •Aggressive camshaft requiring high lift and higher load valve springs, performance pushrods and lifters •High-flow air cleaner and triple-stepped exhaust pipe highly recommended •Feuling also recommends matching this cam with Race Series® oiling system PART #0932-0199 or #0932-0218 •Requires High lift/high load valve springs; see PART #0926-3138 on page 551 •Heavy-duty pushrods are highly recommended see PART #0928-0091 •High lift valve springs, performance pushrods and lifters required •2850 - 6250 rpm range NOTE: Screamin’ Eagle® cylinder heads have high-lift valve springs and do accept the 521 grind cam. 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. NOTE: Feuling fastener kit PART #2401-0994 also highly recommended to help prevent cylinder head cracking; kit replaces the rocker shaft bolts with studs and nuts to help reduce the stress of the rocker shaft standoffs. NOTE: Not for 2023 models with 121” VVT motors.

EASY START CAM KITS FOR TWIN CAM •Start any engine regardless of displacement or compression ratio with a stock starter •Saves your starter and battery; tested for 10.000 starts without running battery down •Allow for easy start by initially reducing crank compression, but once the engine starts and rpm increases, the compression release lobe is centrifugally retracted and the engine runs normally, with full compression, and without any loss in performance •Available in chain drive and gear drive versions •All chain-drive cams include installation kit •All gear-drive cams include 4-gear set and installation kit •Gear-drive cams also available with inner gears only; intended for cam replacement for motors that have already been converted to an S&S gear-drive system NOTE: Installer must check coil bind, valve-to-valve clearance and valve-to-piston clearance. NOTE: Due to the inherent characteristics of gear drives, you may experience more valve train noise. NOTE: Not for models with OEM compression releases. 0925-0443 0925-0453
