Rumors Say The Corvette Will Get A Big New V8 With A Legendary Name
Key Points
- A leaked screenshot from GM’s internal dealer system suggests the 2027 Corvette Stingray will receive a new 6.7-liter Gen 6 Small Block V8, replacing the current 6.2-liter LT2.
- The listed engine configuration includes both direct and port fuel injection and retains GM’s overhead-valve pushrod architecture, pointing to an evolution of the traditional Small Block rather than a clean break.
- If confirmed, this would be the most substantial mechanical update to the base C8 Stingray since its 2020 launch, signaling a deeper refresh for the 2027 model year beyond styling changes.
A new screenshot reportedly said to originate from General Motors’ internal dealer system points to the 2027 Corvette Stingray receiving a next-generation Small Block V8 with larger displacement.
The image, shared on the Corvette subreddit by someone claiming dealership access, appears to show a listing from GM’s Vehicle Locator Service, the internal tool used by retailers to track production details and allocations. The vehicle is ID'd as a 2027 Chevrolet Corvette convertible, with equipment codes that correspond to a Stingray rather than a higher-performance variant.
What has drawn attention, however, is the engine description tied to that listing.
The alleged screenshot shows “ENGINE GAS, 8 CYL, 6.7L, DI, PFI, OHV, ALUM, GEN 6.” That specification closely matches what was reported late last year when rumors started swirling that GM planned to upsize the Gen 6 engines.
The 6.7-liter displacement represents a step up from the current 6.2-liter LT2 used in today’s Stingray, and would be a return of the legendary Chevrolet 409. It's rumored this engine could wear the LS6 designation, which became a darling of the enthusiast world in the C5 Corvette Z06 and Cadillac CTS-V. It's possible the new rumored LS6 V8 could arrive just in time to revive the Corvette Grand Sport for the final years of C8 Corvette production.
If accurate, the change would mark the most substantial powertrain revision for the standard Stingray since the C8 debuted for the 2020 model year. Chevrolet has not commented on the leak, and GM routinely cautions that internal system entries do not always reflect final production specifications.
