HP+ cambox kit

Quieter and smoother engine operation • Increased oil pressure, oil recovery volume and oil circulation
Increases pressure, return volume and engine oil flow
Eliminates wet sumping, blowby and oil-saturated air filters
Single-piece pushrod with .165" wall thickness, high strength, reduces vibrations and increases valve lift
The kit includes: Feuling High Volume oil pump, High Flow billet cam plate, Reaper® series camshafts, hydraulic roller lifters, fixed-length pushrods, Timken/Koyo cam bearings, rocker studs and nuts, seals, O-rings, ARP® cam/crank bolts, washers, moly grease and Loctite®
30% more pressure plate rotor volume than standard for Twin-Cooled™ M-Eight engines
53% greater return rotor volume than standard for Twin-Cooled™ M-Eight twin-cooled engines
27% greater pressure and return rotor volume than standard for M-Eight oil-cooled engines
42% greater return volume through sizing of the passages, ducts and oil holes matched to the engine sump of M-Eight Twin-Cooled and M-Eight oil-cooled engines
68% more oil volume in the crankshaft bearings and connecting rods for M-Eight Twin-Cooled and oil-cooled M-Eight engines.
Tests conducted by Feuling confirm a 50% reduction in engine sump oil level.
Engine temperatures 15-25° lower for M-Eight Twin-Cooled™ and M-Eight Oil-Cooled engines
Oil temperatures 15-30° lower for M-Eight Twin-Cooled™ and M-Eight Oil-Cooled engines
10-30 psi more oil pressure for M-Eight Twin-Cooled™ and oil-cooled M-Eight engines
