Shelby Automobiles says it will modify Ford Shelby GT500s into ultra-performance “Super Snake” coupes for $27,995.

The price for modification is in addition to the cost of a base GT500, which starts at $41,675.

Beginning in late summer, a limited number of GT500 owners can get the Super Snake package applied to their GT500 at the Shelby Automobiles facility in Las Vegas.

The limited-edition Super Snake bumps output from the already-impressive 500 hp produced by the base GT500 to 600 hp.

For customers who don’t mind voiding their warranty, Shelby and his team will further tune the supercharged V-8 to a staggering 725 hp, Ford says.
