LA360 or Magnum?

Woods74,
The power steering pump is the same on a van as a truck or durango, its the bracket thats different between trucks and vans.

Trail Beast,

Dont forget the benefit of factory installed hypereutectic pistons and moly rings. The roller cam is worth the swap alone.

As for your trans, you can easily convert a 4x4 to 2wd by simply swapping the output shaft and OD housing to 2 wd. If you dont want to mess with installing od trans, sell it for $500-$600 to help fund your build or buy a set of bare EQ heads with the $600. I would also at least swap in a better cam as the 5.9 has a pretty weak one factory. You can install a .450" regrind for $175 plus some pushrods.

I would also give serious consideration to using the factory multi port since you want to keep it close to stock and it seems to be a daily driver. You wont be sorry you did.

I considered the trans also, but don't really need it and the FI is just more BS that I'm not ready to deal with on a car I need almost every day.
If I could find a long block LA engine for a good price it would so be in there. :D

Other than that I'll go ahead with a carbed magnum since that can all be dealt with over time on a stand and dropped in on a weekend day.
I think about the biggest change I can deal with at the time is the Mag engine and serpentine system.
I would definitely keep the FI system and computer if it comes with it though, as I might decide to do it at a later time.
