Don't understand cams

I was in the same boat before I built my motor as I knew very little about cam duration and separation numbers and what they mean for the motor and how it sounds as well as runs.
I read everything I could find and discussed it with people who did know, just like you are doing now and finally was comfortable making some of my own decisions on it.

(I ended up with a cam REALLY close to what crackedback just posted for you, and I'm really happy with it):D

Mine is 212-224 and .512 lift on a 110 lobe separation angle and has just a light lope to it but smooth's out the instant you touch the throttle.
