The term is "cam lope" used by old-school engine builders to describe the characteristic variation in sound of an idling engine with big lift and significant overlap cam timing.

Mr Google ..........

Cam “lope” is caused by the overlap when the exhaust valve is opening and the intake valve is closing. The more of an overlap, the longer and lower the sound of the “lope” will be. This is usually a result of a longer exhaust duration.
