What is a 351 Windsor Exactly?
The 351 Windsor (351w for short) is the largest of the Ford Small Block engine family. Ford Motor Company built them between 1969 and 1996. It’s a 90 degree V8 with an overhead valve train. The 351 corresponds to the number of cubic inches displaced by the stoke of all 8 cylinders during normal operation. It’s also commonly referred to as the 5.8 liter for the same reason. The name ‘Windsor’ comes from where the engine was produced… in Ford’s Windsor Ontario casting plant.
Similar in size and shape to the very common 302, the 351 is a taller block. This allows for more piston travel in the cylinder, increasing the cubic inches. To accommodate the increased displacement and increased power, the 351 block castings are beefier in almost every respect.
The Windsor is one of three engines offered by Ford in the 351 displacement. There was also the 351 Cleveland and the 351M (often called the ‘Modified’). The Windsor engine is by far the most common and had the highest production numbers… Ford produced about 8.6 million units at the Windsor plant. It also tends to be the easiest to find aftermarket parts for, due to it sharing many parts with the 302 small block
