well, I am about 90% that your a 4.6 2v. But that being said it is still essentially a mustang engine. If you are looking to tear into it or just want some specs check out ModMax - 4.6 and 5.4 Modular Experts they will cover everything that engine has for performance parts.

Another thing you are going to want to look into is changing out your rear end gears. With that little engine you need to use the top end of your power and with stock gearing your not going to be in it. Get some 4.56's or maybe even lower, that is probably going to be some of your most bang for your buck.

By the way use the search function, performance parts are kind of a never ending question, so there are going to be more threads than you can shake a stick at.
