A cam system to generate valve actuation in an engine that includes a circular camlobe rotated about a first axis is described. The first axis is a preselected distance from the centerpoint of the circular camlobe. The cam system also includes a cam-follower that surrounds the camlobe and that has an inner oval surface with a major and minor axis. The inner oval surface is in moving contact with the circular camlobe during rotation of the camlobe.
