The first ever production big Block V8 Chevrolet engine was the "Single U" series, released in 1958 for passenger car and truck use. This engine was an overhead valve design, with offset valves and unique scalloped rocker covers, giving it a distinctive appearance. The "W" series was produced from 1958 to 1965, with three displacements offered: 348 cubic inches (5.7 L), available from 1958 to 1961 in cars and through 1964 in trucks; 409 cubic inches (6.702 L), available from 1961 to 1965; and 427 cubic inches (6.9973 L), available in 1962 and 1963.
