hmmm you do know these things are factory stoick 220-230 horsepower don't you. You can easily pump it up to 300rwhp, it's been done many times, and there are plenty of fine examples on this board.
As biased as this sounds, the LS1 F-bodies push around 280rwhp stock and in 2001-2002 over 300 stock, quite easily. If you have strong feelings about the Mustang, or just think it's too early to re-sale and get a new car I'd say get a lid, LT headers, and 3 inch x pipe. Those are the first mods I'd do to any car. See where it puts you. You should gain a bit. Then you can either run a small shot of nitrous, or get some more bolts ons. If you get all bolt ons possilbe that should put you pretty close to your goal I'd think, maybe even better.
