A collection of components designed to enhance the performance characteristics of a Ford 460 cubic inch engine. This typically includes a camshaft, lifters, valve springs, and often timing chains or gears. These kits offer various performance profiles, ranging from improved low-end torque for truck applications to increased horsepower at higher RPMs for racing or performance builds.
The impact of these kits on engine behavior can be significant. The altered camshaft profile dictates valve timing, influencing the engine’s power band, fuel efficiency, and overall responsiveness. Historically, these enhancements were crucial for enthusiasts seeking greater output from their engines, pre-dating readily available electronic engine management systems offering similar adjustability. The availability of compatible components in a single kit streamlines the modification process, ensuring proper component matching.
