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.
Yes it is biased but some am I

, but he can acheive what he wants with that Mustang. The LS1 isn't unbeatable and has it's own problems too. They can be beaten by bolt on GT's and he just got the car.
As for the GT, I would go with a ported head and intake job(steen or Fox lake comes to mind), with some VT stage 2 cams, Long tubes w/ full o/r exhaust, U/D pulleys, bigger TB, K&N FIPK, and a SCT Tune.
Stay away from strokers as they are not reliable. If you have a good amount of funds for this car, get an aluminum cobra block(some can be had for 225) and have it bored and turn the motor into a big bore kit. It will have more power, and more reliable than a stroker.
Gears, I would go with 4.10's as they put you into the powerband faster than the 3.73's(which personally I think are a joke on a NA modulat mustang)
