LOL, Hotlap wins the prize!LOL, none of the above...
When debating the name for the new Shelby Mustang, Carroll Shelby asked his associate Phil Remington how many feet it was between the offices and workshop buildings and he replied 350 feet...so it was named the GT 350!!
Really, now that one I hadn't heard...had assumed it was based on flywheel hp rating!Also weird the GT 500 got its name because it was exactly 500 pounds heavier than the GT 350.
