Collection: Manley Performance
In March 1966, Manley Speed Equipment, Inc. was founded by Hank Manley shortly after graduating from college. His interest in performance & racing traced back to 1960 when at 17 years old he rebuilt a 312 CID Ford V-8 engine, installed a camshaft & 3 two-barrel carburetors, & raced a 1956 Thunderbird on the streets of New Jersey. Initially, the line included stainless valves, forged pistons, camshafts, lifters, vanadium valve springs, push rods, & timing chain kits. Today, Manley Performance Products continues to redefine itself in a high-performance aftermarket industry that is constantly evolving. They've developed new products for growing markets such as sport compact, Ford modular, & Chevy LS; as well as maintained their leadership role with the traditional V-8 engine business.
