In July 1976, Ford introduced the XC Falcon, which was the first model to comply with the new pollution regulations specified under Australian Design Rule 27A. This led to locally produced Cleveland V8s and the introduction of the cross-flow (also called the X-flow) six-cylinder. Versions of this engine were produced in North America and, in various guises, used in Australian Falcons through to the XF. Its long stroke and large capacity made for very good 'towing' torque, while its thick castings and relatively loose tolerances gave it a reputation for reliability in spite of abuse.
