Cam Lobe Design

One of the things that is done on stocker cams is having the valve "dwell" at max lift. This is a velocity curve from an aftermarket manufacture, for what is called an exact copy of the Pontiac 744 cam. This cam was used in production Pontiac cars. You can tell a dwell cam because you have an area of horizontal / constant velocity over the nose. Does anyone know of any other OEM production cam that has dwell?
