Firing order on a Ford engine.
Engines come in two types: gasoline and diesel. Spark plugs are used in gasoline engines to ignite the fuel. In diesel engines, the fuel is injected, and combustion takes place when the air is compressed until it reaches a boiling condition.
Additionally, the order in which the spark plugs (in gasoline engines) ignite and the fuel is injected is known as the engine’s firing order (in diesel engines).
Different truck engines with various sizes, capacities, and power outputs have been produced by Ford Motor Co. Seven of these truck engines have been utilized over the years to power various Ford Truck models.
The firing sequences of these nine various Ford truck engines will be covered in this article.
- First, the HO Ford 302 engine: 1-3-7-2-6-5-4-8.
- Ford 302 non-HO engine: 1-5-4-2-6-3-7-8.
Ford 302 HO Firing Order
For the HO Ford 302, the firing order is 1-5-4-2-6-3-7-8, and the distributor rotor rotates in a clockwise direction. On the driver’s side, the cylinders are numbered 1 through 4, while on the passenger side, they are numbered 5 through 8. The firing order is as follows: Cylinder 1 fires first, followed by Cylinder 5, Cylinder 2, Cylinder 6, Cylinder 3, and lastly Cylinder 7.
Then cylinder 1 is used as the starting point once more. The engine rotates smoothly because of the order in which the cylinders are fired. Each explosion generates power that turns the crankshaft, which raises and lowers the pistons.
Ford 302 non-HO Firing Order
For a Non-HO Ford 302, the firing order is 1-5-4-2-6-3-7-8. On the driver’s side, cylinder 1 is the front cylinder, while on the passenger side, cylinder 8 is the rear cylinder. The cylinders are numbered 1 through 8. The firing order is altered, despite the cylinders being placed in the same order as those in a HO Ford 302 engine.
Using a Ford 302 A Ford HO engine’s firing order is 1-5-4-2-6-3-7-8, and the distributor revolves counterclockwise. A small block Ford 302 HO/351W firing order is 1-3-7-2-6-5-4-8.
Consequently, a Ford 302 engine’s firing order is dependent on the model year. The firing order for more recent HO engines is 1-3-7-2-6-5-4-8. The firing order on older Vehicles is 1-5-4-2-6-3-7-8.
LH = 1-5-4-2-6-3-7-8 and RH = 1-8-7-3-6-2-4-5 are the firing orders for early 302 engines, which are the same as those for the 260 and the 289 engines.
The firing order of the 351 W engines, with LH = 1-3-7-2-6-5-4-8 and RH = 1-8-4-5-6-2-7-3, was utilized by the subsequent 302 engines (marine). They switched over between 1972 and 1974.
Additionally, the firing order for a non-HO Ford 302 engine is 1-5-4-2-6-3-7-8. Cylinders 1, 2, 3, and 4, which are the ones closest to the firewall, may be seen on the passenger side of the engine while looking from the front.
Cylinders 5, 6, 7, and 8 are located on the driver’s side, with 8 being close to the firewall. The same configuration applies to HO 302 engines as well.
Furthermore, remove the valve cover and position cylinder number 1 at top dead center to see if the engine has the usual non-HO firing order (TDC). By manually starting the engine, you may do this.
It is near to that location when your finger touches air flowing from the hole of spark plug number 1.
Use the timing marks on the damper at that point to reach TDC. The engine will then be manually turned once more, this time clockwise. Take note of the order in which the intake valves open to verify the above-mentioned firing order. You are certain if it confirms the sequence.
It actually makes no difference whether the order is altered. However, note the order in which each cylinder’s intake valves open. You will learn the firing order for the 302 Ford engine by doing this.

What Is The common Firing Order For A Ford Engine?
Ford engines uses a variety of firing orders, but the most popular one is the 1-3-7-2-6-5-4-8 pattern. The majority of Ford V8 engines, including the 5.0L and 4.6L engines, follow this firing order.
This firing order makes the engine run more smoothly and evenly while also enhancing efficiency. Additionally, it facilitates starting and lessens engine vibration. The various firing orders for Ford motor engines are shown here.
How Do I Figure Out The Engine’s Firing Order?
The firing order of an engine may be discovered in a few different ways.
• One is to refer to the owner’s manual or a repair manual for the particular make and model of your car. The firing order diagram for your engine may be found in these publications.
• Examining the spark plug wires is another method for figuring out the firing order. The spark plug wires are often color-coded and attached to the plugs in a certain order. It’s crucial to first refer to a schematic or your owner’s handbook because the order will vary depending on the engine.
• Don’t panic if you need to figure out an engine’s firing order but don’t have a schematic or manual on hand. Other approaches to determining it include:.
• One approach is to examine the engine directly. The majority of the time, the engine’s cylinders will have numbers. The firing order is frequently printed on the engine or can be found in the owner’s handbook.
Using a timing light is a further method of figuring out the firing order. With the use of this instrument, you can watch when each spark plug ignites by attaching it to the spark plug wires. You can tell which spark plugs are firing in which order by keeping an eye on the timing light.
