General Motors has announced the return of its iconic 350, 400, and 409 V8 engines, but this time with modern technology and improved efficiency. The new 6.7-liter, 535-horsepower LS6 will debut in the 2027 Chevy Corvette Grand Sport, while the 5.7-liter small-block truck motor will make its debut in the 2027 Silverado half-ton, replacing the old 5.3-liter L83 V8.
The new 400 (6.6-liter) will supersede the 6.2-liter L87, and both are based on a common design. Chevy says the 6.6-liter V8 will be the most powerful naturally aspirated V8 in the half-ton segment. However, the company has not yet released official power numbers for the new engines.

"From tough towing scenarios to the daily demands our customers put on their trucks, these next-generation V8s were engineered and proven to perform in the real world."
With the addition of these new V8s to the lineup, GM is expanding production of its new V8 to its Tonawanda, New York, and St. Catharines, Ontario, facilities. The new LS6 is already being assembled in Flint, Michigan. We'll learn more about the new 5.7- and 6.6-liter V8s closer to the 2027 Silverado's on-sale date later this year.
