Fastest Stock Motored 87-93 GT Mustang You've Seen

[Mustang_GT_90]

Ok boys and girls I've got a question for you. I'm about to do some major work to my motor, AFR heads, cam, holley systemax I'm going hardcore but I've yet to make a pass this season and would like to do some little stuff to my car before I run to see how fast I can go on the stock motor.
My question is this, what is the fastest STOCK MOTORED 87-93 Mustang GT that you've seen.
Weight reduction, gears, exhaust, computer chips, pulleys stuff like that it's all good...I'm talking stock injection as in tb injectors, stock valve train, stock heads and stock cam.
Anything else can be done to the car. The fastest I've gone to date on slicks on motor is 13.3.
That's with an actual stock motored 90 GT with exhaust, electric fan, pulleys, gears, and a short belt. So post up and lets see what everybody has seen. I have two friends that have dipped into the 12s one with a speed density car and one with a mass air car.
Thanks in advance...oh yah if you post up please tell what was done to the car as in gears weight reduction stuff like that...
