Back in the day when muscle cars dominated the American auto consciousness, the name Steve Yenko was regarded as a wizard of performance modifications. As the man who ran Yenko Chevrolet of Canonsburg, Pennsylvania, Yenko oversaw an aftermarket division that gave birth to the Yenko Camaros, considered today as one of the most sought-after Camaros among enthusiasts of the pony car. Yenko Chevrolet’s run was brief, though, as the company stopped making customized Camaros in the early 80’s, and it wasn’t until 2009 when the name returned to the spotlight with the announcement that General Marketing Capital Incorporated (GMCI) announced its ownership of the Yenko trademark. Fast forward to today and the name “Yenko” has officially returned, albeit on a different model altogether. This, ladies and gentlemen, is the 2017 Yenko S/C Chevrolet Corvette Grand Sport, a heavily modified Corvette that comes with upgrades galore, none more impressive than a new engine output of 800 horsepower and 750 pound-feet of torque.
