This component group is designed to replace the factory camshaft and related parts in a 460 cubic inch (7.5L) Ford engine with a more performance-oriented roller cam system. It typically includes a roller camshaft, roller lifters, valve springs, retainers, locks, and timing chain set. The primary function of this setup is to improve engine performance by optimizing valve timing and reducing friction compared to a flat tappet cam system.
The advantages of using this upgraded system include increased horsepower and torque, improved engine durability due to reduced wear on the camshaft and lifters, and the ability to run more aggressive camshaft profiles without premature failure. The evolution of this technology is rooted in the pursuit of enhanced performance and reliability in internal combustion engines. Historically, high-performance engines have incorporated roller cam systems to achieve superior valve train dynamics.
