Dave, the 12V 5.9s are good to go with a vacuum pump already part of the package,but servicing the AC pump, nightmarish in the stock Dodge installations, becomes total FUBAR in the custom set ups.
The MAIN issue with setting up a good 5.9 in Black Betty would be dishing and lowering the main front crossmember about 3" to accomodate the deeper Cummins pan.
Relocating the starter's a bit of a headache, as well.
Maybe Unicorn piss will run a mite better than this low sulfur bio-fuel though ?
