The Ford truck engines use a lot of different parts than a car. Usually the sodium filled valves and really small ports, different distributor, water pump ect. Low revving engines.
I found this info, might help, note the intake port differences.
In 1952, the overhead valve Lincoln 317 cubic inch Y-block replaced the obsolete 337 Flathead, adding 4 horsepower despite having 20 cubic inches less displacement. A 341 cubic inch version was introduced in 1955, and a 368 c.i. version followed in 1956. The oil pan rail of the block extends below the main bearing cap parting surface, and is the reason for the "Y" name. The deep-skirt block design resembles the letter Y when viewed from the end. This engine is similar to the Ford Y-block, although the Lincoln version is larger. Note that the Lincoln Y has more common side-by-side intake ports while the Ford Y uses the unusual stacked "upper and lower" intake ports. The distributor is in the rear. Bore spacing of the Lincoln Y is 4.63". This engine family was also used in heavy-duty Ford trucks in 279, 302, and 332 cubic inch versions up to 1963. The Lincoln Y was replaced by the MEL in passenger cars in 1958.
