For 17-19 M- Eight Twin-Cooled Motors. 521 RACE SERIES® CAMCHEST KIT FOR M-EIGHT. Requires high lift valve springs. Bulletproof your engine with maximum reliability. Kit includes Race Series oiling system: billet 7075 oil pump, Race Series lifters and High Flow billet aluminum camplate. 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. Cam responds well with increased bore and/or increased compression. 465 RPM range 1850-5950. 521 RPM range 2250-6250. Made in the U.S.A. - Part Number - 0925-1216
