You would be hard pressed to claim anything other than what number you currently have for ID. Even if it is a 1925 car with an earlier motor, you would still have to find a 1925 numbered motor block to get it up to snuff.

Ford has a long history of changing or updating parts on the fly. This obsoletes earlier parts if Ford made the choice not to produce them in their legacy replacement part scheme and the replacement parts were either a direct fit or could be made to fit. The other fact is that many owners took it upon themselves to repair or update their cars with what ever parts were available including salvage yard parts.

With enough persistence, you can make it into a 1924 or a 1925 if you choose to go by judging standards and performing the research to get the right stuff but it will take some time and more money to get there. It may be easier to build it utilizing the characteristics of the majority of parts you have in hand then update or change it as you go. If you want a 1925 then you will still have a lot of 1924 parts. You can never have too many old Fords but your significant other (if you have one) may not think the same way.
