cams that just idle roughly sounding like this: https://www.youtube.com/watch?v=P7M27YmIT70&t=60s
and cams that cause actual lope like this: https://youtu.be/oaJ3w_fAdoI?t=37s
What's the physical difference between them, and what do they cause the engine to do that makes the difference between an arrhythmic popping idle and a rhythmic lope?
I'm aware both are somehow related to valve opening overlap, but clearly there's a difference between the 2.
