Feuling Race Series 472 Camchest Kit
Oceanside, California based Feuling Parts' complete camchest kits "include all the necessary components from top to bottom of the camchest, conveniently packaged under one part," says Drag Specialties.
"These combination kits not only ensure each individual part is designed to work and function together, but to do so in total harmony - they take the guesswork out of the ordering process and provide the engine builder maximum reliability, peak performance and the coolest engine/oil temperatures obtainable".
These complete camchest kits include Feuling high volume oil pump, high flow camplate, 472 Reaper Series camshafts, hydraulic roller lifters, fixed length pushrods, Timken/Koyo cam bearings, rocker arm studs/nuts, gaskets, O-rings, ARP cam/crank fasteners, washers, moly paste and Loctite.
Race Series kits include a Race Series oiling system, Race Series lifters, high flow billet 7075 aluminum camplate and billet 7075 aluminum oil pump, which is 50% harder and stronger than the factory pump, holding tighter tolerances under temperature and deeper scavenge kidneys over Feuling's HP+ oil pump (deeper scavenge kidney ports over the HP+ series for even more scavenge flow volume).
Feuling 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.
The kits deliver +30% more pressure gear volume, +53% more scavenge gear volume and +27% more pressure and scavenge gear volume over stock in M-8 twin-cooled motors.
They deliver +2% more scavenge volume with port sizing, matched passages and holes to the engine case for M-8 twin-cooled motors and M-8 oil-cooled motors with +68% more oil volume to the crankshaft and connecting rod bearing and 15-25/15-30 degrees cooler engine temperatures for M-8 twin-cooled motors and M-8 oil-cooled motors (plus 10-30 more psi of oil pressure).
The increased oil pressure, scavenge volume and engine oil flow mean a quieter and smoother engine operation, reduced wet sumping, blowby and oily air cleaners - magnets in the oil pump help protect gears and pressure relief valve.
Feuling says that test results show +2 hp gain and 2 ft/lbs of TQ gain to the rear wheel on M-8 models and a -50% reduction of engine sump oil level.
