Description: 1979 Trans Am. My favorite car of all time because it was my first car. This car came with a 403 that we all know was rated at 185 hp. I don't know how hp was calculated, but this car out ran practically everything that came up against it where I lived. It was strong on the bottom and 140 mph on the top. I don't know what it will do now because I take a little better care of it and am tired of spending money on the restoration.
