The Ford engineers developed a new V-8 configuration in a small block engine. It displaced 260 cubic inches. This is the engine that got Shelby’s attention after Chevrolet turned him down when he asked to use their small block in his Cobra project. This is the engine that Shelby and Moon stuffed into the first AC body.
