As far as I know it's all looks. Sticker package, wing, and side exhaust that you can buy all separately. The "Boss" was a concept stang that never went into production. Just like the Super Stallion and the Mach III. The concept Boss was supposed to have about 500 or so hp. But anyone, now, can buy the graphics, etc to make it look like a "Boss" mustang. Kinda like buying a Saleen graphics kit or wing, etc. Nothing special about that "Boss" that you are looking at. And that was back in 94 or 95 using either a 302 or 351W but I can't remember the motor. That 97 is the 4.6L.
