416 Stroker-Powered 2017 Chevrolet Corvette Grand Sport 2LT Convertible

Description

"A Stingray with an enormous amount of grip...A Z06 without the completely absurd power." Car and Driver knew exactly what made the 2017 Corvette Grand Sport so special — the kind of neck-straining, corner-straightening grip that forced smiles from elated drivers' faces.

Underneath its aggressively styled, flared wide body, the Grand Sport wore a high-tech chassis with a widened track, Z06 suspension bits, and big brakes hidden by bigger wheels wearing sticky performance tires. This combo resulted in roadholding well over 1g and intense deceleration from speed — impressive performance from a luxurious, smooth-riding machine that was equally at home on a daily commute as it was on the racetrack.

And while the stock 6.2L LT1 made 460 horsepower, this 12,000-mile example is even more powerful. Its LT1 V8 was professionally built into a 6.9L (416ci) stroker utilizing a high-end Callies and Diamond rotating assembly. It was dyno tested to 497 rear-wheel horsepower.

It is finished in Arctic White, has a Black convertible top, and features eye-catching Adrenaline Red leather upholstery.

This 2017 Chevrolet Corvette Grand Sport 2LT Convertible is now offered with engine build paperwork, a dyno sheet, a clean CARFAX Vehicle History Report, and a clean Texas title in the seller’s name.
