I'd take a VM diesel before ever touching a chev 6.2/6.5 V8 diesel.
4BD1T (factory turbo model) is similar NVH to the 300tdi.

Buy a complete and registerable Perentie 6x6, swap over the engine, box and PAS, add Intercooler and boost away.
Sell the rest for all up change over cost of probably $3K.
Yes the 4BD1T is heavier.
