The firing order for the Ford 460 should be the same among all engines from the series, but other Ford V8 engines have different orders. In this guide, we will take a closer look at the Ford 460 firing order.

What Is the Firing Order for Ford 460?

The firing order for Ford 460 is counterclockwise 1-5-4-2-6-3-7-8. This is the same order for most of the engines in the Ford V8 460 series, so you can avoid mixing up the spark plug wires and using the wrong order.

The firing order usually differs across vehicles, specs and engine capacities, but you can determine the order for a majority of Ford 460s beforehand. The firing order is a fixed configuration between the crankshaft and the camshaft, so it must not be changed. If it’s delayed or wrong, the spark will be delivered to the wrong component.

The Ford V8 460 is one of the most popular big block engines from the manufacturer and was produced from 1968 to 1990. The engine was mostly used in Ford pickups and is a top option for those looking for an aftermarket crate motor engine. The eight-cylinder motor offers impressive power and durability.

Ford 460 models built before 1972 offer 365 horses at 4,600 RPM and 485 pound-feet of torque at 2.800 RPM. The engine is cheap and ideal for trucks and big cars that have enough room under the hood for a large motor. But you should keep its order in mind when installing.

Firing Order for Other Engines

Aside from the Ford V8 460, other engines come with separate firing orders, which you must not mix up. The firing order for the Ford 5.0-liter, 351W, 251M, 351C and 400 engines is the same, counterclockwise 1-3-7-2-6-5-4-8. The Small Chrysler engine has an order of clockwise 1-8-4-3-6-5-7-2.

The Big Chrysler order is counterclockwise 1-8-4-3-6-5-7-2. Then, Chevrolet and Buick are clockwise 1-8-4-3-6-5-7-2.

What Is the Aim of the Ford 460 Firing Order?

The aim of the Ford 460 firing order is to compress the fuel-to-air mixture and produce the combustion needed to move the car wheels when the spark plug fires. By following the order, the car can move with the right fuel/air mix when the spark plug fires.

In the V8 engine, the cylinders are arranged with two banks on each side of it. It is number 1-8, with the 1-4 on the passenger side and the 5-8 on the other side. But, the cylinders only fire based on the order that you have arranged the spark plug in.

When each piston rotates, the electric signal goes through a spark plug wire from the rotor to the spark plug. It is this electric current that triggers the spark plug to fire. Also, there would be gasoline in the chamber from the fuel injector. Then, the spark in the chamber ignites the fuel and air mixture.

This explosion fills the chamber with exhaust, pushing the piston down. The next cylinder in the firing order would rotate the piston back up and follow the same process, firing the spark plug. Based on the firing order, all the cylinders would follow the same process to fire the spark plug, providing power to the wheels.

How Do You Put Spark Plugs in the Correct Firing Order?

You put the spark plugs in the correct firing order by changing the spark plugs one chamber at a time. Disconnect the wire from the chamber, remove the plug, and insert the new plug. Then, reconnect the loose spark plug wire.

This method is very easy, and you won’t have to remove the distribution cap from the Ford engine. But, if your wiring is mixed or you’re not sure about how your car works, you would have to follow the steps below.

To put the spark plugs in the correct order, you need the owner’s manual of your car, screwdriver, work light, and protective gear. You also need a lot of concentration and time to get it done.

1. Get the Owner’s Manual

The first thing you should do is get the owner’s manual to understand your spark plug wires. Suppose you have the owner’s manual for your car. You can find out where the different parts are and also the firing order, which has been mentioned earlier.

2. Locate the Number 1 Terminal

Based on the owner’s manual, you can find the number 1 terminal. If you don’t have the manual, you should check if any of the spark plug caps have a mark or look different from other firing terminals. Most manufacturers mark the number one terminal. The number 1 is always the first in the order.

3. Connect the Number 1 Terminal

Once you find the number 1 terminal, you can connect it to the first cylinder of the engine. The number 1 cylinder is the first in the spark plug firing order. You will see the numbers 1-8 on the cylinders, making it easy for you to connect them. If it is not numbered, you can consult the owner’s manual.

4. Connect the Spark Plug Wires

Now, you can connect the other spark plug wires. Now that you’ve connected the number 1 firing terminal to the number 1 cylinder, you have seven more to connect in your Ford 460. So, you would connect terminal 5 with the fifth cylinder. Based on the firing order, the next connection is terminal 4 with the fourth cylinder.

Then, you can do so for terminals 2, 6, 3, 7 and 8, to the second, sixth, third, seventh and eight cylinders located on opposite sides of each other. After connecting it, you should make sure that it is secure, close the hood and start the car.

What Happens if You Use the Wrong Firing Order?

If you use the wrong firing order, the car will misfire and idle, or it will not start at all. If you connect the wrong cylinder to the wrong spark plug and start the car, the engine will misfire and might also idle roughly.

If you got more than two wires wrong in your connections, the car wouldn’t start. If this happens, you should go back to the steps mentioned earlier and ensure that you connected the correct firing terminal to the cylinders. Manufacturers number the spark plug wires and cylinders to prevent problems like this.

With the numbering, you can correctly arrange the wires from the cylinder to the terminal. Also, a wrong order can wear out your crankshaft bearings. It can also cause the engine when you start it, or it would backfire through the intake. In worst cases, you would have a muffler explosion.

In general, using the wrong order would cause the engine to run poorly, or it won’t run at all. If it manages to run despite not firing on all cylinders, it would cause damage to your engine components and can also stop at any time. If your Ford 460 engine is weak, it can also damage it completely. If you’re unsure about arranging the plugs, contact a mechanic.

What Determines the Ford 460 Firing Order?

The Ford 460 firing order is determined by plugging the correct spark plugs into the cylinders to produce minimal vibrations when driving and prevent backfiring. The order was designed for balanced load distribution on the crankshaft by pistons and efficiency.

The parameters of the Ford 460 firing order include the number of cylinders, heat distribution, alignment of the crankshaft, vibrations of the torsional plane, cylinder arrangement and crank journal. Conflicting spark plug wires can stop your engine from starting, which is why the order and its parameters are important.

The spark plug wires are managed by the motor computer or ignition module. This receives signals from the crankshaft sensor to know which piston is reaching the end of its compression stroke process so that the next plug in the order can be fired.

If you’re unsure of how to arrange your plugs despite knowing the order, you should ask someone with mechanical expertise.

What is the Ford 460 Firing Order Distributor Cap?

The Ford 460 firing order distributor cap is a separate part that covers the distributor and the rotor in the start system. The distributor cover is needed to support the passage of electrical current to the spark plug from the ignition or start coil.

The cap gets damaged quickly, so it’s important to check it whenever you maintain your car and replace it. The Ford 460 protects and shields other parts, which makes it susceptible to damage.
