GM is expected to bring out the 2027 Corvette Grand Sport next year which will feature a new 6.6L V8 engine called the LS6. Our friend Rick Conti says he has an unofficial sound file of the engine running from inside the car.
Rumors of a new Gen VI Small Block V8 in two sizes – 6.6-liter and 5.7-liter – are rumored to be coming sooner rather than later with the 6.6-liter V8 headed for the 2027 Grand Sport, Stingray and E-Ray.
