That's the question, Ray.
The answer is, Ford NEVER put VIN numbers on their engines. GM did but not Ford.
It becomes obvious if you have a 1955 with casting numbers that show ECZ 9425-B, something is wrong because this 4-bbl manifold came out in 1957 as B7A 9424-B. That is the ONLY way to know what year castings were made.
Here we are some 60 years later, you can see that when components are changed (except for the block), engine serial numbers mean nothing because it is not the same engine any more. Ford simply specified certain cubic inch engines in their specific model year cars and trucks and kept track of the casting number revisions. The casting numbers verify authenticity, service parts or hot rod changes. - Dave
