Chevy big block Gen VI 454 C.I.D. V8 1996-2007 Chev BB Hydraulic Roller Lifter (each) Speed Pro SPHT2279
Product Information
Speed-Pro hydraulic roller lifters provides significant friction reduction while greatly increasing horsepower and fuel economy at the same time. Valves open more quickly from a fully closed to a fully opened position with a hydraulic roller lifter when compared to a conventional flat lifter. This then provides for enhanced performance, quieter engine operation, more horsepower and still allows for proper vacuum and idling capabilities
