Ok, so I'm not a mechanic or anything here but this is my basic understanding of the camshaft. The camshaft controld when your intake and exhaust valves open and close. By moding the cam you change when your intake and exhaust valves open and close. From my understanding, too much variation can have less of an impact than a mild variation or "mild cam" depending on the modifications that are done to the car. I've got a camshaft in my basement if you'd like picture of how things work and what it looks like.
