This Chevy Nova looks like exactly what it is on the outside — a garage-built driver car with old-school flavor and nothing flashy about it. What’s hiding underneath is a supercharged LSA V8 putting down a dyno-verified 557 horsepower to the rear wheels, with an estimated 650 to 700 at the crank. It’s the kind of sleeper that wins by surprise, not spec sheet. Watch to see what happens when the supercharger whine finally gives it away.
