though is an excellent choice for 114” and larger cubic inch engines with added compression ratio. Though not required, ported cylinder heads will complement the cam and add even more pulling power throughout the range. The stock throttle body again produces an excellent powerband, though use of a high flow throttle body HP+ series kit External fastener kit for '17-'19 Baggers will increase peak power numbers. A high flow exhaust system and air cleaner is highly recommended for optimal performance and matching with Feuling’s Race Series oiling system is recommended. High lift valve springs are required, and heavy duty pushrods are highly recommended. Valve lift open close duration at 50” lift and TDC lobe centerline is .508 21.5 BTDC 36 ABDC 231 .180 97.5 at the intake and .511 45 BBDC 9 ATDC 243 .146 104.25 at the exhaust with an rpm range of 2,250 - 6,250 and overlap of 30.5. At the top of the range of M-8 compatible Reaper cams, Feuling describes its 592 grind as “the Big Nasty” requiring you to “put your big boy pants on and get serious with bore size, ported cylinder heads and high flow throttle body.” An aggressive camshaft, it requires high lift and higher load valve springs, performance pushrods and lifters. A high flow air cleaner and triple stepped exhaust pipe are highly recommended, and Feuling also recommends matching this cam with its Race Series oiling system. High lift valve springs are required (such as the Feuling Beehive valve spring kit); heavy duty pushrods are highly recommended. Also seen here, Feuling camshaft kits for Milwaukee-Eight engines include camshaft, lifters, inner cam bearing, cam/crank hardware and a gasket/O-ring kit that allows for use of the factory one- piece pushrods or the company’s own “optional and recommended” heavy duty 0.165” wall one- piece pushrods. HP+ Series kits include the HP+ hydraulic roller lifters for 405 and 465 grinds; their Race Series kits include Race Series hydraulic lifters, which have a External fastener kit for '18-'19 Softails full .200” of total travel designed with a slower bleed down rate to handle heavy valve spring pressures and increase engine rpm before valve float. They feature increased roller clearance for steep ramped camshafts and clearance for the Milwaukee-Eight front exhaust camshaft lobe flange. These are the kits recommended for 465, 521, 508 and 592 grind installs. Newly available from Feuling, M-8 ARP dress-up external fastener kits for 2017 - 2019 Baggers and 2018 - 2019 Softails are made in high grade stainless steel and include 12-point engine case bolt kits, external engine kits, external primary and transmission kits and chassis and trim kits for Softails and Road Glides.
