Ford 302 HO & 351W Firing Order Diagram 1-3-7-2-6-5-4-8 with Distributor Cap

This schematic shows the firing order and cylinder layout for Ford HO (High Output 302) and 351 Windsor V8 engines. The document contains two diagrams: at the top, a circular distributor cap diagram showing the terminal positions (5, 6, 2, 7, 3, 1, 8, 4 arranged around the cap) with the rotor indicated pointing to the number 1 terminal; below it, a top-view engine block diagram labeled 'HO & 351 W' with the firing order '1-3-7-2-6-5-4-8'. The engine diagram shows cylinder numbering with cylinders 5, 6, 7, and 8 on the left bank (front to rear) and cylinders 1, 2, 3, and 4 on the right bank (front to rear). From this document a reader can determine how to route spark plug wires from the distributor cap to the correct cylinders for a 5.0 HO or 351W engine, since it correlates the cap terminal positions with the engine's cylinder numbering and the firing sequence. The diagram is credited to 'Jrichker' and dated 01-05-2007. No part numbers, torque specs, or wire colors appear in the document.
