Small-Block.
Big Legend.

An all-new take on an American classic.

Born from the Jet Age, the iconic 350 engine sent Corvette, Camaro, and Caprice to the races before establishing itself as a versatile workhorse. Designed, engineered, tested, and backed by General Motors, the all-new 350 combines unyielding heritage with modern precision machining. And that adds up to another generation of service.
