Ford introduced the "Y-block" OHV engine to replace the venerable flathead in 1954. This engine had the same displacement as the old flathead, 239ci. For some reason, they did not perform well and this displacement engine was only built for one year. In 1955 they went to 272ci as a standard engine. The new Thunderbird had a 292ci engine which was already available in the Mercury line. In 1956 they introduced the 312ci. Thunderbird special. The Y-block series of engines were good engines but they were pretty thirsty. Some of the slightly "different" aspects of these engines were the way you had to set the timing, which someone already mentioned, the external oil pump with a tube running through the oil pan to the pickup, and the front crossover exhaust pipe. There were aftermarket kits available which supplied a left side exhaust manifold and a block off plate for the right side where the crossover pipe was removed and you had dual exhaust. The mention of those Fords of yesteryear bring back a lot of good shade tree memories.
