REAPER® CAMS FOR 17-23 M-EIGHT •Produce more power and torque in the riding rpm range, improving throttle response, acceleration and fuel mileage •Smooth camshaft lobe ramps are easier on valvetrain components and eliminate excessive valvetrain noise and wear •Dyno proven and track tested •Made in the U.S.A. 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. 0925-1163 PART # DESCRIPTION EMIS* 0925-1163 405 chain drive cam 2 405 CAM •Produces a wide powerband that increases torque and horsepower throughout the entire rpm range •Direct bolt-in replacement for M-Eight engines; can be used with stock valve springs, pushrods, lifters and exhaust •Will respond well when used with slip-on mufflers or full exhaust system and a high-flow air cleaner •Feuling recommends mufflers with smaller cores for the best low-rpm power •1700 - 5700 rpm range 465 CAM •Produces solid bottom-end performance and substantial gains above 2800 rpm compared to the stock cams •Direct bolt-in replacement for M-Eight engines; can be used with stock valve springs, pushrods, lifters and exhaust •Will respond well when used with slip-on mufflers or a full exhaust system and a high-flow air cleaner •Use of performance valve springs is not required but may result in a quieter, smoother-running valve train •Responds well when combined with increased engine bore and/or engine compression •1850 - 5950 rpm range 472 CAM •Great all-around camshaft and Feulings go to for 4 1/2 stroke 114” - 117” engines looking for a little more than the 465 grind and wanting a bolt-in •Has a great bottom end with substantial gains above 2800 rpm when compared to stock •Use of performance valve springs is not required but may result in a quieter, smoother-running valve train; see PART #0926-2973 or 0926-2974 on page 534 •Responds very well to increased bore and or compression, exhaust system and air cleaner 508 CAM •The Grim Reaper 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 •Feuling recommends matching 508 cam with Race Series® oiling system PART #0932-0199 •Requires high lift valve springs; see PART #0926-2973 or 0926-2974 on page 534 •Heavy-duty pushrods are highly recommended; see PART #0928-0091 •2250 - 5900 rpm range 538 CAM •Aggressive camshaft with a nasty sound •Revs up fast and pulls hard in engines with big bore cylinders, modified cylinder heads, intake, compression and exhaust •The REAPER 538 grind will shine in 124” 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 Race Series oiling system •High lift valve springs are required on stock cylinder heads; see Feuling Beehive valve spring kit PART #0926-2973 or PART #0926-2974 on page 534 •SE cylinder heads have high lift valve springs, but will need to be verified •Heavy-duty one piece pushrods are also highly recommended; see PART #0928-0091 on page 538 •2250 - 6250 rpm range 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;
