Oil pump is 50% harder and stronger than the factory pump, holds tighter tolerances under temperature. Race Series hydraulic lifters have a full .200" of total travel designed with slower bleed-down rate to handle heavy valve spring pressures, increase engine rpm before vavle float and feature increased roller clearance for steep-ramped camshafts and clearance for the M-Eight front exhaust camshaft lobe flange. Quieter and smoother engine operation. Increase oil pressure, scavenge volume and engine oil flow. 15-25 degree cooler engine temperatures. 15-30 degree cooler oil temperatures. 10-30 more PSI of oil pressure. Eliminate wet sumping, blow by and oily air cleaners. Heavy duty .165" wall one piece pushrods reduce valvetrain harmonics and increase valve lift. 465 Reaper cam is an accelerator, producing solid bottom-end performance with substantial gains above 2800 rpm compared to stock.
