YaMZ engines.

[RUTruckFan]

A question to any experts on Russian truck engines
so the Kraz-255 has the YaMZ-238 engine in it and (according to wikipedia) the Ural 4320 comes with a YaMZ-238M2(there's also the V6 available).
what are the differences between these 2 units and what is the Displacement of the M2 unit in the Ural?
