Oceanside, California performance specialist Feuling Parts has these cam chest kits for M-8s to “bulletproof your engine with maximum reliability.”
Available in their HP+ or Race Series kits, CEO Luke Leatherman says they are quieter and result in smoother engine operation, increased oil pressure, 42% more scavenge volume with port sizing, matched passages and holes to the engine case and 68% more oil volume to the crankshaft and connecting rod bearing.
Said to deliver 15-25 degree cooler engine temperatures, 15-30 degree cooler oil temperatures and 10-30 more PSI of oil pressure, the kit reduces wet sumping, blow-by and oily air cleaners.
Heavy duty .165” wall one-piece pushrods reduce valvetrain harmonics and increase valve lift with test results showing +2 HP gain and 2 ft/lbs of TQ gain to the rear wheel on Milwaukee-Eight engines (plus as much as 50% reduction of engine sump oil level).
Specs for the water-cooled oil pumps include 30% more pressure gear volume over stock and 53% more scavenge gear volume over stock; for the oil-cooled engine oil pump 27% more pressure and scavenge gear volume over stock. An optional Feuling X ARP bolt kit is available for the high flow camplate and HP+ or RS oil pump combo.
The kits include the Feuling high volume oil pump, high flow billet camplate, Reaper series camshaft, hydraulic roller lifters, fixed length pushrods, Timken/Koyo cam bearing, rocker arm studs and nuts, gaskets, O-rings, ARP cam/crank fasteners, washers, moly lube and Loctite.
The kits are available in three different camshaft options. The 405 “is a true workhorse, producing a wide powerband, increasing torque and hp throughout the entire rpm range when compared to stock and will respond well with slip-on mufflers and/or complete exhaust systems and a high flow air cleaner (rpm range 1,700 - 5,700).
“The 465 Reaper is an accelerator, producing solid bottom end performance with substantial gains above 2,800 rpm when compared to stock; this cam will also respond well with increased bore and/ or compression (rpm range 1,850 - 5,950).
“The 521 Reaper grind has aggressive pulling power with a “nasty” sound, shines in 114” and larger cubic inch engines. This cam will respond well to ported cylinder heads and increased compression ratio. High lift valve springs are required, and a high flow exhaust and air cleaner are recommended (rpm range 2,250 - 6,250).”
The HP+ Series kits include the HP+ oiling system consisting of billet 6061 aluminum high volume oil pump, high flow camplate and HP+ hydraulic roller lifters; for 2017 and up oil-cooled M-8 models.
The Feuling ‘Race Series’ kits include a ‘Race Series’ oiling system - the billet 7075 oil pump, ‘Race Series’ lifters, high flow billet 7075 aluminum camplate; and billet 7075 aluminum oil pump, which is said to be 50% harder and stronger than the factory pump, holding tighter tolerances under temperature.
‘Race Series’ hydraulic lifters have a full .200” of total travel designed with a slower bleed down rate to handle heavy valve spring pressures, increase engine rpm before valve float and feature increased roller clearance for steep ramped camshafts and clearance for the M-8 front exhaust camshaft lobe flange.
