There are also a few other subtle differences. For example, pulley width. I don't remember right offhand what the sizes are but I have a 216 car engine and a 216 truck engine and the fan belt and pulleys are different widths - the truck belt being wider. I am not sure on this one but I don't think that a car 216 could be hand cranked but the truck engine I know can be. (in '51 and before at least. However, unless you are looking for EXACT restoration no one will notice or care.
