Yes, I believe that engine date is fine. Unusual yes, but I know of one other 03E car with a similar engine date. Having what appears to be the original block also helps confirm it.
Did you notice the car was backhalved?

I'd have to see more data on your car, but as Mike's car shows, that axle date doesn't seem out of line.
One caveat to these exceptions - they don't happen every month. It might not be fine in an end of April car, for example.
