Ford 351 Windsor Firing Order Diagram and Cylinder Numbering
Ford 351 Windsor firing order 1-3-7-2-6-5-4-8 with cylinder-bank numbering, counterclockwise distributor routing, TDC procedure, and diagram.
The Ford 351 Windsor firing order is 1-3-7-2-6-5-4-8. Cylinders 1-2-3-4 are on the passenger bank and 5-6-7-8 on the driver bank, front to rear; the distributor rotor turns counterclockwise viewed from above.
The Ford 351 Windsor firing order is 1-3-7-2-6-5-4-8. Cylinders 1-2-3-4 are on the passenger bank and 5-6-7-8 on the driver bank, front to rear; the distributor rotor turns counterclockwise viewed from above. A firing order is the sequence in which the cylinders begin their power strokes. It is not the same thing as cylinder numbering, distributor-cap clock position, or ignition-coil connector order. Confusing those references can create a no-start, violent backfire, dead cylinders, or a diagnostic trail that looks like a fuel or mechanical problem.
Use the verified order only after identifying the engine family and camshaft. Classic engines can accept camshaft swaps that change the required sequence, while modern coil-on-plug engines have no distributor cap to route. The table, bank diagram, and procedure below keep those concepts separate and show how to confirm No. 1 on compression before moving any wires.

Select each cylinder to walk through the firing order. Cylinder-bank numbering and distributor direction must match the identified engine family.

| APPLICATION / ITEM | SPECIFICATION | NOTES |
|---|---|---|
| Firing order | 1-3-7-2-6-5-4-8 | Ford 351W order |
| Passenger bank | 1-2-3-4 | Front to rear |
| Driver bank | 5-6-7-8 | Front to rear |
| Distributor rotation | Counterclockwise | Viewed from above |
The 351W order was later adopted by 5.0 HO engines, but that does not make every 302 a 351W-order engine. Identify the engine and camshaft independently.
Which 351 Windsor firing order applies?
Do not identify a 351W only by displacement; the 351 Cleveland and 351 Modified are different engine families. This distinction matters because the engine can look nearly identical from above. Treat the camshaft or engine assembly as the authority when parts have been mixed. A firing order cast into an intake, copied from a generic decal, or remembered from another V8 is not enough to identify a modified engine.
The application table separates the order, cylinder banks, and ignition-system notes. Read all columns before routing. The first number in 1-3-7-2-6-5-4-8 is cylinder 1, but the physical No. 1 terminal can appear in different clock positions when a distributor has been installed on a different gear tooth.
Bank numbering and verification on the 351 Windsor
Ford small-block bank numbering places 1–4 on the passenger side and 5–8 on the driver side.
The 351W order was later adopted by 5.0 HO engines, but that does not make every 302 a 351W-order engine. Identify the engine and camshaft independently.
Ford 351 Windsor specifications can change by model year, engine, platform, wheel, and installed component. Confirm the VIN or engine identity, part numbers, fastener condition, and the current manufacturer instructions before service.
Procedures used with this specification
These steps are the same for every vehicle in this family, so they are documented once rather than repeated on each page. The values above remain specific to this Ford 351 Windsor.
