Starting to collect parts for my v8 swap, the squirrels need to find a new home instead of my engine bay. I found an 01 Durango for cheap in my city, like sub $1k. My issue is I believe the 2000+ were PCI and my 99 TJ is CCD, do y'all think it's worth it to find a 99 donor to make the swap easier? Unfortunate that 99 is my only option, 00+ is PCI and I can't go 98 or before due to emissions and federal stuff. I plan to use the 46RE auto but I read somewhere that I need to change the input of my 231J to a 231 spline as supposedly the 4 bangers got a 21 spline input.

Only the 2.5 with the manual AX-5 was 21 spline. All 2.5 auto, 2.4's and 4.0's have a 23 spline input TC case. So the 42rle, 30rh, 32rh, AX-15, NV2550, NV3550, NSG-370[4 or 6 cyl version] will be 23 spline. Your profile says you have a 30RH, meaning your TC is a 23 spline. So you're solid :)

And yeah... my 4 squirrels need to find a new habitat or make 2 more friends.

You can find a Dodge engine wiring harness on Ebay for around $150-300 so if the engine and transmission out of the Durango are GOOD and you can get the whole rig for under $1K it might be worth it. You'll also need a 5.9 auto PCM from a 98-01 Ram truck which you can find on Ebay for under $200.

Yes you'll need a new input gear for you transfer case since the 4 cyl had a 21 spline & the 6 cyl & the V-8 transmissions have a 23 spline output shaft. You can either source a new NP231 with 23 spline or just get the input gear and swap it out on your transfer case.

Here is a chart to help you out a little as far as which rigs are CCD or PCI

The 2.5 auto is 23 spline, correct?
 
This is good to hear, thanks to you both. I found a 99 for a little cheaper than the 01, both have running drivetrains but have issues with brakes or dented panels or other stuff that makes no difference to me. Either way the motor will get a fresh tune up/ probably swap some seals while it's on a stand. Plan was to buy a running donor, pull the driveline and whatever else I need, then either sell the rest to a scrapyard or put in the effort to part it out to try and make the money back and end up with a free motor/trans save for some labor.

Some things to know.

Most Durangos & Dakotas & Grand Cherokee's have some type of security installed on them so the PCM most times will not work. Getting a PCM from a 98-01 Ram truck in the lower trim levels are your best bet.

When you are working on the engine you'll want to do the plenum gasket for sure. And then if you can identify any leaks & where they are coming from.
Depending on the mileage you will want to look at the timing chain also if it's got more than 150K miles.

Having a donor rig sitting there is always your best option for those odds & ends stuff.
 
These are both 180k+ rigs, I figured I'd have to do a full refresh on the motors, timing chains, lifters, gaskets, might even do fresh head gaskets and bolts. I've been reading about the plenums, more reading yet to do. May even have the trans rebuilt at a local shop to get fresh steels and clutches and hopefully avoid any nonsense within 10k or so of doing the swap. The squirrels are alive and happy for now so I can take the time to do it right without being under the gun.

Even though many like to claim the LS is some sweet engine the 2 Magnum engines I've taken apart that had 150K + miles on them both looked new on the inside. The bores looked almost new and the blocks didn't need to be bored .010 or .020 over. They stayed stock bore & the cranks used stock bearings.
It's worth it for you to do a basic rebuild on the engine & transmission prior to installing them. And it's a good thing to have your heads checked for cracks around the valve seats. If they catch them soon enough they can be repaired.
You'll also need to decide if you are going to run block hugger headers or stock exhaust manifolds?

The plenum gasket is a FOR SURE thing and don't just replace the gasket but get the fix it lit.
I have 246K miles on the 5.2 in my 1997 Ram pickup BTW.

This is what happens when it isn't caught and the head cracks bad.

Haven't decided on a header yet. After seeing this, I'll pull the heads and drop them off at a machine shop to get flattened and have the seats checked. Looking at the Hughes plenum kit and I think I'll go that route.

If you decide you want to use the stock exhaust manifold see if you can find some 92-94 manifolds as they have a larger opening.

If you go with headers Summit Patriot headers seem to do OK.

Let me know if I can be of any help. Always glad to try where I can.
 
Makes sense. I've looked at RAMs but in this area the cheapest I can find one is a 150k mile for 2K and that's with a blown trans. I don't think the cost of the PCM or other little bobs offset the savings of the durango I found and just buying a RAM PCM.

Many people have used one of the other platforms and then just picked up a Ram PCM. When I did my swap the first time I ended up having to go thru 3 PCM's before I finally found a good one. But I was buying used units not one from a PCM repair company. The ones on Ebay now all seem to be from a repair company.
