50 modified Corvette Grand Sports are to be produced. Hey, Hellcat! There’s a new horsepower king in town. The 2017 Chevrolet Corvette is featuring an 800-hp Yenko and was unveiled before Barrett-Jackson debut at an event held at the Southern California-based purveyor of restoration and aftermarket parts for Mopar and Chevrolet muscle cars, Classic Industries.
This car starts life as a conventional Corvette Grand Sport built by Tom’s River, N.J.-based Specialty Vehicle Engineering (SVE). SVE then increases the LT1 V-8’s displacement from 6.2 liters to 6.8, replacing many components in the process and uses the famous Yenko name under license. SVE’s version is fitted with a forged steel crankshaft and aluminum pistons, and CNC ported and polished cylinder heads.
As the cherry on top is a 2.9-liter twin-screw supercharger fed by the fuel system from the LT4 V-8 found in the Corvette Z06. This version is good for 800 hp and 750 lb-ft of torque. The transmissions offered by Chevrolet in the Grand Sport are a seven-speed manual or an eight-speed automatic.
The rest of the Yenko modifications seem to be merely cosmetic. Throughout the exterior, interior, and on the brake calipers Yenko badges are added, just everyone to notice that it’s a Yenko.
SVE unveiled the Yenko Corvette to the public at the 2017 Barrett-Jackson Scottsdale sale that took place on 1/14/2017. The package costs $46,000. You can choose between a coupe and convertible, but only 50 will be built.
This Yenko, unsurprisingly, does not meet the state’s strict emissions regulations, unless you live in California, most likely because SVE was unwilling to pay for CARB certification for such a small run of aftermarket engines.
