My first and only time to the track gave times very similar to some of the times above.......13.83 @ 99.97. Air was ok, about 70, but the track was greasy, messy and slick. My stock truck had around 5,000 miles on it when we went to the track.
Ford claims 13.9 at 100mph. The magazine article you refer to said that they had 50 degree air that day.... I think my truck would run that time in that kind of oxygen-rich environment.
