The 351 Windsor, or 351W, was built in Windsor, Ontario, and it is part of Ford's small-block family, sharing components with the 302, or 5.0L. It has a taller deck height, unique firing order, and longer stroke. While not as performance-focused as the Cleveland, it is the most common of the three. The 351W was produced from 1969 to 1997 and found in everything from muscle cars to trucks.
Made in Cleveland, Ohio, the 351 Cleveland, or 351C, was Ford's go-to performance small block, known for its high-flow heads and strong crankshaft. It came in two versions: the 2V for mainstream cars and the 4V for performance models. Produced in the United States from 1970 to 1974, and until 1982 in Australia, its limited run makes it rarer and more expensive to build than the Windsor.
Derived from the 400, the 351 Modified, or 351M, had a taller deck and used the big-block 385-series bellhousing pattern. Built from 1975 to 1982, it was primarily used in trucks and large cars, making it more of a workhorse than a performance engine.
Despite sharing displacement, these engines served different roles. The Cleveland powered high-performance cars, the Modified handled utility duties, and the Windsor, produced for nearly three decades, was by far the most versatile and widespread.
