I Need Help And Guidence... :)

I was wondering if there is anyone in here that could help me figure out what all I shoud and shouldn't do to my 1993 5.0 LX Hatch. I am wanting to add more horsepower. If anyone can help please contact me on MSN Messenger so we may a conversation. My e-mail is LHS_2002@hotmail.com thanks a lot

I dont have a lot of mods the only ones I have are, new headers, new cam, cold air intake, new plugs and wires, and a full flowmaster exhaust. I just turned 21, I have always love stangs, and this is my 3rd, but this is the first one I have tried to do stuff to, because my first was an 86 5.0 and it was kind of beat up, and my second one was a '93 lx nothcback 2.3l. 4 cyl.. So I am just now learning. thanks.
