Ford Sidevalve engine

The Ford Sidevalve is a flathead engine from the British arm of the Ford Motor Company, also called the English Sidevalve. It had its origins in the 1930s Ford Model Y and was made in two sizes, the 933 cc 8 HP and the 1,172 cc 10 HP, the horsepower figures being the British road tax ratings and not real power outputs. Early engines had no water pump and relied on thermosiphon cooling, as the Model T engine had, and a pump was added in 1953 when the engine was re-engineered for the 100E models. It powered many small Fords, farm and commercial vehicles and a marine version, and the German Ford plant used it from the Ford Koln of 1932 to the last rear-wheel-drive Taunus 12M in 1962. Production stopped in 1962, when the Kent engine replaced it in Britain and the Taunus V4 in Germany. Tuners fitted special manifolds, twin carburettors and inlet-over-exhaust heads from Willment and Elva.
