Rocker Arms and Adjustable Valvetrain Geometry

Understanding rocker arms and adjustable valvetrain geometry helps you pick the right components for your engine buildThe typical four-stroke engine is made up of hundreds of parts. These parts are all designed and engineered to work together to make a prescribed amount of power, torque, engine longevity, and other parameters for the engine's design (or more accurately what management has told the engineers it needs to do for a specific cost). As long as these parameters are kept in check, the engine will provide the horsepower, torque, longevity, et al, it was designed for. However, if you begin to make changes to that internal combustion engine, be it a camshaft upgrade, new high-flow cylinder heads, or any number of hard part upgrades, you have effectively changed that engine's engineered design and steps need to be taken to ensure that the new parts are engineered to work with the other new or existing parts of the engine.
