You want 850HP? For less than the price of a new Shelby GT500? Sure! But the rest of the car isn't included.
This is awesome, but I have no idea why anyone would buy it other than for some absurd vintage showpiece that they're trying to pass off as original, despite costing themselves tons doing it.
...or maybe there's some secret underground group of uber-wealthy who put together ideal-spec vintage racers, or sleeper street cars, and run high-strung race motors in them for some kind of elite circuit since they can afford to rebuild the motors every 400 miles.
Please let it be the latter.
