Mercury added a quarter-inch of stroke to the 239, raising total displacement to 255. Some European marques and Cadillac had V8 engines decades before Ford developed the engine that would yield affordable performance and create the basis for hot rodding. This engine can be identified in the field by counting the cylinder head studs, of which there are 21 per side. They have been shown here to help identify the general starting number. For powering the fuel pump, the camshaft is fitted with an extra cam located in the bearing on the flywheel side.
