I have a 1998 Gt completely stock. Ive had since 99 and I want to make it go fast. Do I pick up a wrecked ford with a 5.4 and swap motors bolt on a 6 speed and get the computer reprogrammed or do I go for a crate motor straight from ford racing and if so whats the best bang for the buck....tired of my boring old 98 gt

I have a 95 GT and replaced the 302 with a 347 Stroker. Depending on the money you want to spend, the Pro-Charger Super Charger makes my Mustang impossible to catch. Tremec 5 speed trany and now I am making my chasis stiffer and replacing the rear end suspension. So with a little time, money and patience, you can have a super fast car that's easy to drive.
