The assembly in question represents a performance upgrade for the Ford 302 cubic inch (5.0L) engine. It includes a camshaft utilizing roller bearings instead of the traditional flat tappet design, along with necessary supporting components such as lifters, valve springs, and retainers. This facilitates improved engine performance and durability.
The adoption of such a system offers several advantages. Roller cams reduce friction, leading to increased horsepower and torque output. Enhanced valve train stability at higher engine speeds and prolonged component lifespan are also notable benefits. Historically, this upgrade represents a move towards more efficient and reliable engine operation compared to older flat tappet systems.
