help me to understand cams

Thanks for all the reply's fellas and the links too. I understand its going to take a long time to understand it all but im young so i got time to learn. Ive spent a lot of time talking with delta camshaft choosing the right custom grind for my build. Ive been very particular with choosing my parts to make sure they all work together. Im just searching for info so i figured asking here would help me on my path to enlightenment.
