stock time?
13.6 to 13.9 is what mr mustang would hope we run. Just kidding unit

I ran 13.06 @ 106mph with a k&n and whisper lid at Houston Raceway park. I had 6000 miles on the car. Be careful of doing that now if you have T-tops. They are inforcing a rediculis rule ...but that is for another thread.
Good luck
