What about the GM 4.7HO engine from the Jeeps? Or the 5.7 Hemi?
I assume gearbox adapters are the issue?
And you can't use the Jeep box and transfer because the front prop-shaft output is on the wrong side (LHS not RHS)?
I'm "between" Landies and driving a Jeep GC Overland with the 4.7HO motor, and I must say, I can't think I've driven anything nicer.
Not a vehicle I'd take into rough African or Aussie bush, but I've done the Lesotho highlands in it, and it was extremely good off road.
Now THAT motor in a Deefer 110 SW would just about cause me to have some type of indecent physical manifestation...... :o
