For adapting the Kent Crossflow for front wheel drive the ancillaries were repositioned, and the cylinder block shortened by . This decision was taken in order for the engine to fit transversely across the Fiesta engine bay, whilst still allowing the transmission unit to be comfortably removed for clutch replacement. This difference however means that very few parts of the Valencia engine are interchangeable with a Crossflow. However, Ford ended up installing the Crossflow engine into the Fiesta anyway, when the market demanded a 1.3L capacity, and later a 1.6L version for the North American market models – ultimately the 1.6L Crossflow also was used in the Mk1 Fiesta XR2 when the North American market Fiesta ceased production in 1980.
