348 to 409: The story of Chevrolet’s first big-block
The Chevrolet W engines mark the birth of Chevrolet’s big-block performance era and stand among the most legendary powerplants in American automotive history. Produced from 1958 through 1965, the W-series engines were bold, innovative and brutally powerful for their time.
