Bro, do some reading in the performance mod section of this board. It WILL answer a majority of your questions. Not tryin to be a dick, but do some research and if you still don't understand, ask some questions. In short: bigger cam needs a higher stall. Gears would be beneficial as well as a trans cooler so you don't fry your trans. Are you planning on building the trans to handle the power you want to make? Also, budget plays a lot into what you can and "should" do for mods.

Remember you can have only two of three things: fast, reliable, cheap
