Restoring 1969 dodge dart GTS after 24 years

Here is the fender tag and the trunk ledge and the radiator support number as well and the dash vin.
For the fender tag it says E55 which is a 340 but I also included the K frame member that it shows it had a 383 which is what the hood inserts have (I removed it from the body for the first time) . Going back to my previous post the guy that brought the car back from Arizona also said it was an original 383 4 spd. car, I have the exhaust manifolds as well. That is why I am looking for what the "027" engine order code stands for??
Does anybody know how to search for an original owner in another state (Arizona).
