The original LAV-75 used a 650hp gas turbine; I replaced it on the A4 with a 750hp diesel (I put "a modified form of a Caterpillar heavy tractor engine" and gave the engine a name that sounds like a Caterpillar engine, but is not actually used by the company.

In my post which resurrected this thread a few weeks ago I mentioned the engine used in the M8 which is a 6 cylinder diesel closely related to the HEMTT's engine. I'd go with that engine or something very similar.
Ah what the heck, I'll just quote myself from that post:

The Cadillac Gage Stingray and Stingray II light tanks actually use the M977 HEMTT's 8V-92TA engine as well.
