The Ford family of Windsor engines surely belongs in the realm of automobile royalty with Ford making Windsors in many different models for over 40 years from the 1960s to the 2000s. The 351 Windsor engine powers some world famous muscle cars, including the Mustangs of the 1970s. In fact, the Boss 351 crate engine, which Ford Performance Parts still produces for racing enthusiasts, is a modified version of a 351 Windsor block. The Windsor engine underwent some changes over the years, which is why it is important to pay attention to the model year when purchasing engine parts on eBay. The 351 Windsor heads, for example, vary by sizes with the early 1969 and 1970 engines using larger heads for better performance. The engine heads made from 1971 to 1976 are smaller than the previous engine models and the models made after 1977 share the same head size as the 302 engine. In general, many automobile enthusiasts prefer the earlier versions of the 351 Windsor engine made out of heavy cast iron metal than the later lightweight versions because they hold up better under high-performance expectations.Shop the large inventory of motors, parts, accessories, and complete Ford car and truck engines!
