2013 Camaro SS LS3 vs 2007 Shelby GT500

Both cars are manual transmission. My car when this video was recorded was completely stock with the exception of a CAI intake. His GT500 was stock as well.
It was a 1/2 mile roll race from ~40mph on a closed course.
This first time I had a passenger (person who recorded this vid) and my windows were down. I lost by a nose.
I went against him again with a passenger delete and the windows up and beat him by about a length and a 1/4.
Both runs were great.
