There is no way to correlate an engine number with the vehicle number unless the car has original paperwork. If no paperwork then about all you can do is look at the vehicle number and using the sequence portion see if the approximate time of production during the model year was in approximate relation to where the engine number falls in the total engine production. If the two roughly fit together such as each number being in the first, middle or end of production you can be fairly sure it is original. Here is the 51-54 engine number ranges and models they were used in.

A 54 convertible would have only had one engine and the proper one for the car would start M6xxxxxx. That was the most powerful S-8 Packard produced and was only one year. A motor with any other letter or number means the engine has been replaced at some point
