Many 428, 390 and 360 blocks had no casting part numbers, only a date code.
You can try looking in your spark plug holes at your pistons. If they are flat top, then they are not factory 428 pistons which had a small dish in the center.
You can try using a thin plastic rod in a spark plug hole to check the stroke.
When all else fails, pull the pan and check the crank and/or pull a head and check the bore/stroke.
