I'm not sure what you are asking. If you mean what are the numbers then there are a few variances. If this is what you want I will be glade to try to explian them all.

when someone says lift and duration, i don't know what that meens. but i think if you have more lift and duration, you get better proformace.
i would like someone to explain how it works and how i can tell the differance between a stock, mild, or high proformance cam.
or what ever else it has to do with.

thanks

Well, in a high-performance car you want high lift and low duration. The reason for the low duration is because in the strokes of an engine, there is a quick overlap in which the intake valve is open as well as the exaust valve. And the lower the duration, the less time that this is (or the total rid of time) where they are both open, resulting in the less loss of air, and high compression. Of course, this is another one of those things where you have to watch with higher compressions, as there as also disadvantageous results if not well thought out.

Good luck!

Also, when you do get a new cam, you have to watch. Believe it or not, this affects very many things. You can't just change the cam, and forget about everything else. For instance, a carb is highly affected by the cam. If it has vacuum purposes, the cam can alter vacuum at difference levels, therefore altering the carb.

Just some things you need to keep in mind.
