looking at a 89 or 91 grand wagoneer for donor vehicle

I have a line on 2 grand wagoneers one a 91 and the other a 89. my question is can I swap the entire drivetrain into my 90YJ (engine,tranny and TC) besides motor mounts what else should i need. Also what is involved in swapping out the rear axle (D44) any major issues there? I have a great running 4.0 in there now but I think I am getting the urge for a V8.

Personally, I'd avoid it like the plague.

The Dana 44 swap is okay I guess, but then you have the 6 lug issue to deal with (6 lug rear, 5 lug front) or swap both axles and spend a LOT of time swapping out a Dana 30 that is a great axle to begin with.

The AMC 360 shares nothing with the Dodge 360, so parts are limited & it's never been a "powerhouse" V8 even on it's best day.

IMO, if you want a V8, find a 5.7L Chevy with 700r4/NP231 combo and get a Ford 8.8 rear axle. You'll get a lot more bang for your buck.

There is no situation that cannot be improved with a small but well-placed explosive.

That 360 in the waggy is a serious gas PIG. The two i had averaged 9 mpg. 3 speed with no OD.

Your limited slip differential sucks.

From what I have heard from local shops around here you can take a D44 down to 5x4.5 so you can keep your wheels and tires you currently have. Take that with a grain of salt though as I have yet to even start the search and serious research part of that swap. I am going to do D44's on both ends and call it a day despite all the bashing they receive. I will never run a 4 letter F word in any of my rigs so my only axle options are Chrysler corporate (8 3/4 isnt a bad axle at all) or Danas. 44's see a nice balance between power handling and size for what I want to do. Besides I like to think that while wheeling I am generally pretty easy on my rigs so I bet my D35 would even last under my 5.2 for quite some time.
As far as the AMC 360, its a great motor. Sure there isnt a ton of aftermarket support for it anymore, but you can still do a lot of things to them and make good power, mostly down low where you want it to be anyway. If you play your cards right you can get an AMC that has a 727 behind it. What that means is you can throw a later trans (OD 42RH anybody?) behind it and give it a chance of making some better fuel mileage for you. Basically it all amounts to how much research do you want to do and how much effort are you willing to put into the swap.
And for those suggesting a GM drivetrain swap, take a minute and think, why are they so plentiful in the junkyards? Leave em where they lay (and belong) and go with a brand known for something other than 100K mile throw away toy cars.
