Looking at the hole pattern for the cylinder head, I think that is a 4.4" bore block. If so, it is most certainly a BSD333 block with 4.4" stroke, and it is of the newer cross hatch (waffle) type. That means that you need a lot of new parts inside to make it work. You also need another injection pump (or have the old one rebult) and other injectors.
Ask the seller what the bores are.
You might go for a short motor BSD333:
but parts add up; Bolt sets, oil pump (if not included), injection pump. injectors...
Send an email to these guys:
and ask if they can get you a proper block.
If money is not the issue, they have remanufactured engines, plug and play:
