What Is the Firing Order for a Ford 351 Windsor?

The firing order for a Ford 351 Windsor is 1-3-5-7-2-6-5-4-8, which is different than most of the company’s other V-8 engines. Ford starts numbering its cylinders from the front left of the engine, with cylinders 1–4 on that side and cylinders 5–8 on the right.

By making sure the 351 Windsor is firing in the right order, the right spark plug will light and the engine will keep running smoothly. If a car is running well before the plug wires are taken off, like when spark plugs need to be changed, they are probably in the right order.

Labeling them before taking them off the spark plug is the best way to make sure they stay in that order. If they get switched around by accident, the owner can put the right wire back on each plug if they know the firing order.

Ford made the 351-cubic-inch Windsor because people wanted more powerful stock engines. It came out in 1969. Gasoline was cheap, and the first engines with a lot of power had more than 300 horsepower. As emission rules got stricter, Ford had to lower the power output.

The 1973 Mustang only had 169 horsepower. Ford used the 351 Windsor engine in many of its cars for a long time. But because people want better gas mileage, it doesn’t have this engine in any of its cars as of 2014. Ford’s motor sports division still sells the 351 Windsor as a crate engine.
