I have to question the original premise that the Shelby AC Cobra is indeed a ford legend.
No doubt the Shelby AC Cobra is indeed a great legend, but I might suggest that to call it a ford legend is not entirely accurate. It is more a legend, that was back then, powered by a ford engine.
Today of course, the best legendary engine to power the best legendary car is the Chevy LS series.
Well that's what I want to put in mine when I build it anyways .....
