Shelby American was kind enough to shoot a gallery of photos as they assembled the first 2013 Shelby GT350 in Gotta Have It Green. The photos show the entire transformation starting with a base 2013 Mustang GT to the end result depending upon what the customer orders. Shelby GT350 come naturally aspirated with around 450 horsepower or you can opt for the Supercharged version that delivers upwards of 600 horsepower. Most of the assembly takes place at the front of the car with the interior receiving a bevy of upgrades. Check out the whole process in the photos below.
