Camshaft overlap explained
WebA camshaft is a simple device that converts rotary motion into linear or up and down movement. The lifter follows the shape of the lobe, imparting lift as the eccentric moves … WebOne of the camshaft's most fundamental tasks is to transform its rotating motion into linear motion or lift. This is accomplished on a typical Chevy V-8 with 16 lobes (an intake and an exhaust)--all of them ground to an …
