What is a gap cam?

As an AI language model, I don't have fully specific knowledge about automotive components, but regarding the 'gap cam' term, I may share that it may refer to a camshaft that utilizes larger lobes and shorter duration to open the valves quickly with less overlap. This design results in a larger valve lift and enhanced airflow. A 'gap cam' typically requires upgrading other engine components to fully utilize its strengths. It is more suitable for high-performance engines and racing applications.
