General Motors will reintroduce a lineage that shaped generations: the sixth-generation Small Block V8 family is set for 2027, taking a cornerstone of American motoring into a fresh technical chapter. The first engines will appear in the Chevrolet Silverado, GMC Sierra, and the C8 Corvette.

According to 32CARS.RU, the headline update is a reworked 5.7-liter V8 focused on better fuel efficiency. It replaces the current 5.3 L84 and adopts an improved Dynamic Fuel Management system that can deactivate cylinders under light loads. The unit nods to the celebrated LS1 and LS6 once installed in the Corvette and Camaro, a pragmatic way to save fuel without dulling the engine’s character.

The second engine, a 6.6-liter, is aimed at pickups and performance models. Rumor has it this will form the basis for a future Corvette Grand Sport. Output is expected to top 520 hp, with torque exceeding 700 Nm—figures that point to effortless thrust where it counts.

GM has already invested $854 million to modernize U.S. plants for the new series. Production will shift to Kentucky to improve quality control; earlier iterations, it’s worth recalling, were hit by large-scale recalls.

The new Small Block is more than a routine update—it reads as a return to classic V8 values. GM appears to have blended familiar torque and durability with modern tech, keeping that unmistakable American V8 heartbeat under the Corvette’s hood.
