TL;DR
Chevrolet is now producing new versions of its classic V8 engines—the 350, 400, and 409. These engines will power upcoming 2027 models, blending vintage appeal with modern technology. The move signals GM’s focus on traditional V8 performance amid shifting industry trends.
Chevrolet has officially announced the production of new 350, 400, and 409 cubic-inch V8 engines for its 2027 vehicle lineup, marking a return of these iconic displacements after decades. This development is confirmed by GM officials and signals a focus on traditional V8 performance in upcoming trucks and sports cars, despite broader industry shifts toward electrification.
Chevrolet’s new 350, 400, and 409 V8 engines are based on modern design principles but pay homage to the classic engine displacements of the past. The 5.7-liter (350 cubic inches) V8 will debut in the 2027 Silverado half-ton, replacing the older 5.3-liter engine, and is expected to deliver a combination of power and efficiency. The 6.6-liter (400 cubic inches) V8 will succeed the 6.2-liter L87 engine, claiming to be the most powerful naturally aspirated V8 in the segment, although Chevrolet has not yet specified exact horsepower figures.
GM has confirmed that these engines are undergoing extensive testing and validation to meet durability and performance standards. Production of the new engines is expanding to GM facilities in Tonawanda, New York, and St. Catharines, Ontario, with the LS6 being assembled in Flint, Michigan. The engines are designed to meet the demands of towing, daily driving, and off-road use, aligning with Chevrolet’s reputation for durable trucks.
Reviving Classic Displacements for Modern Trucks
This move demonstrates Chevrolet’s commitment to traditional V8 performance at a time when many manufacturers are shifting focus to electric vehicles. For enthusiasts, the return of these displacements offers a nostalgic yet contemporary engine option, potentially boosting sales among traditional truck buyers and performance enthusiasts. It also signals GM’s confidence in internal combustion technology, emphasizing durability and power for the foreseeable future.

After decades of discontinuation, GM’s recent announcement aligns with a broader industry trend of revitalizing traditional engine sizes with modern technology. This development comes amid ongoing discussions about the future of internal combustion engines versus electrification, with GM affirming its commitment to V8s for now.
“We pushed these engines through an extensive testing and validation process to make sure they deliver the durability, capability and dependability Silverado customers expect.”
