Randy, it appears that the engine block number might tell you what you have. For the 56 Dodge, the block starting with D61 was a Coronet, D62 was a Royal and a D63 was a Custom Royal. The V8 block numbers on 58 Plymouths were LP2-H, LP2-L and LP2-M. I would assume these are in ascending order with the top of the line last. I got these out of a 1960 Motors Manual. Hope it helps.
