Callaway Cars fitted the SC757 Package in October 2015, adding a GenThree TVS2300 supercharger, high-flow intake, triple-element intercooling, and carbon-fiber engine covers to the LT4 V8. The package is rated at 757 horsepower and 777 lb-ft of torque, with power sent through the seven-speed manual gearbox. The seller acquired it new, and all of the under-10,000 miles were added under current ownership. Recent work includes an oil change in December 2025 and replacement engine trim.
