The [[Chevrolet]] '''big block''' is a series of large displacement [[V8]] engines that were developed in the [[USA]] during the 1950s and 1960s. As American automobiles grew in size and weight following the [[Second World War]] the engines powering them had to keep pace. Chevrolet had introduced their popular [[GM Small-Block engine|small block V8]] in 1955 but needed something larger to power their medium duty trucks and the heavier cars that were on the drawing board. The decision was made by [[Chevrolet]] to develop an all-new design for large-displacement use. This engine family had two generations, the "W" series, and the Mark IV series. | The [[Chevrolet]] '''big block''' is a series of large displacement [[V8]] engines that were developed in the [[USA]] during the 1950s and 1960s.
