396021 is defonetly a 455 there should be a F (68-72) or Fa (72-75)on the right side of these numbers as you face the motor from the front .The F,F1,F2.... is on the back of the block behind the fly wheel that is the casting run number. On the right front side of the motor under the head where it meets the block there is a small pad with nubers on it. These should match the last six numbers on the vin if its the origenal motor.
