mustang gt intake, get rid of two of the four cats,install a cold air intake,install headers and enlarge the size of exhaust. also incorperate an x pipe . use larger fuel injectors and fuel pump and have your ecm reprogramed by someone who works with this type of engine. that should put you close to 350hp. then if more is wanted try a supercharger or turbo or nos. all just a way of cramming more air per cycle into the cylinders . remember speed is how fast can you spend !!!
