Thanks making it clear that it is what Kevin found in the Ford data as the build date of the car. Too bad we don't have record of when the car was started in this example
...Has anyone come across an engine assembly date that is the same as the cars build date?
No don't have anything close to that in my records
Guess it could possibly be a mis-stamp
Did you look for the other dates on the oil pan mating surfaces?
Not sure how the engine could have been assembled, finished transported to the car plant, installed and the car completed all in the same day.
