A performance upgrade component designed for specific Ford 390 cubic inch engines, this aftermarket assembly typically comprises a camshaft employing roller bearings instead of traditional flat tappets, along with compatible lifters, springs, and related hardware. The setup aims to improve engine efficiency and power output.
The adoption of a roller bearing design significantly reduces friction within the engine’s valve train. This reduction translates to increased horsepower and torque, improved fuel economy, and extended component lifespan. Historically, these enhancements represent a move away from older, less efficient designs in favor of modern performance technology, offering tangible benefits for classic engine builds.
