The new Corvette Grand Sport debuts an all new LS6 engine generation for Chevy. It gets a larger 95-mm throttle body and a tunnel ram intake as well as a very high 13:1 compression ratio. But perhaps the most important thing is more displacement, measuring 6.7-liters compared to 6.2 before. As a result it makes 535 naturally aspirated hp and 520 lb-ft of torque. Then again, maybe the most important thing is how it sounds.
