February 21st, 2023Finally being recognized as an international supercar, the Chevrolet Corvette is better than ever. Down in Houston, Texas, a firm called Late Model Racecraft (LMR) is kicking it up a notch above that. This clip takes us inside a 2019 Chevrolet Corvette ZR1 build that delivers some big results.

With it’s factory supercharged 6.2-liter V8 engine, this ZR1 posts maximum output readings of 650rwhp and 663 lb.-ft. of torque. That’s in line with factory numbers.
