The video focuses on setting the proper push rod length in an engine to achieve the correct preload on the rocker. The presenter begins by discussing the process of adjusting the push rod length to approximately 7.450 inches and checks for zero lash by ensuring the rocker cannot be moved. They then use a torque wrench to achieve a preload of about 90 to 100,000 on the lifter. The presenter mentions that Summit sells adjustable push rod lengths to fine-tune this measurement. After testing the push rod length with various engine locations, they confirm that the preload is achieved at around 95 to 100,000, which is the desired setting. The method includes checking the preload on multiple corners of the engine to ensure consistency.
