Camaros already have a lot of power. Before adding more I recommend looking at improving the efficiency of what you already have. Upgrade the rear differential/cradle bushings to Pedders (or the brand of your choice) first before doing anything else. You'll be amazed at what a difference that alone will make.
I've put a lot of info in my project thread that might be useful to you:

Hopefully that will give you some ideas and welcome to the addiction called "modding" lol.
