Ferguson pretty much copied the Ford 9N design, had a set of Ford 9N blueprints to work to, and even most part numbers are the same as the Ford. When Ferguson and Ford shook hands in November, 1938, the very next day Ford engineers were busy designing the new 9N. Ferguson wanted the tractor to have an overhead valve engine as well as 4-speed transmission, but the Ford Engineering Team vetoed these and ended up with a 3-speed tranny and a flat head 4-cylinder engine. The 3-pt hydraulics are pretty much the same. The Ford 4-speed transmission wasn't introduced until July, 1947 when the 8N Ford Model was released. By then Ferguson was competing with Ford with his TE-20 and TO-20 models. The OHV engine was a much better motor and the extra 4th gear was a big plus as farmers wanted a faster highway speed to get to and from their fields. The Ford team would have had a much better tractor with an OHV engine and 4-speed tranny. The major issue with Ferguson Continental engine was they were prone to cracked blocks, mainly around the cylinder walls. Basically HP is the same and both are great strong work horses.
