Supercharged 6.2-liter (376 cu. in.)
638 hp @ 6500 rpm, 604 lb-ft @ 3800 rpm
Like the LS7 engine in the Z06, the Corvette ZR1′s engine is hand-built — but that’s about the only similarity. The 6.2-liter LS9 engine is supercharged to the tune of 638 hp, making it the most powerful production Chevrolet car engine in history. And the ZR1′s top speed of 205 mph makes it the fastest production Chevrolet of all time. It also has titanium connecting rods for extra strength, as well as special cast-iron cylinder liners to fortify the aluminum block.
