The Speed Shop is open to the public and will focus on enhancing the performance of all muscle cars, be it Detroit Three or foreign brands.

“While we specialize in all-American, high-performance cars, our experienced team can work on just about everything,” said Shelby American vice president Gary Davis.

Shelby American can install headers, cams, heads, cold-air intakes, superchargers and any other performance parts, according to the company. The shop will even do work on sand buggies. It just installed a top-of-the-line chassis dyno to check its work.

Modifications made to any Shelby Cobra, GT500, Super Snake or Shelby GT at the shop will be included in the official Shelby registry.

In other Shelby-related news, the company says it is nearing completion of its Shelby GT500 40th Anniversary and 427 Super Snake packages. They should be finished by the end of 2010.

The 427 Shelby Super Snake package commemorates Shelby's first sponsorship of the Las Vegas NASCAR race and includes adjustable caster/camber plates, Shelby badges, a strut tower brace for the 605-hp version, a blower badge on the 725-hp version, a Carroll Shelby signature and a certificate of authenticity.

The GT500 package includes special wheels and badges, a suspension upgrade, body work, exhaust and some dress up for exterior.

The remaining packages can be ordered from Shelby American Sales at (702) 942-7325.
