Lately I've been messing around with 90s and early 00s Jeeps and I'm starting to get comfortable with fuel injection, engine management computers, and wiring harnesses that weigh 50 lbs and are as thick as my bicep. There are tons of late 90s Grand Cherokees in the junk yard with 5.2 engines. There might be even more in Dodge trucks and vans. They appear to still have distributors, so the computer control is limited to operating the fuel injection. You could probably get everything you need to do the swap, including the engine, for a quarter of what it would cost to buy one of those aftermarket fuel injection setups. I was wondering if anyone had transplanted one of these into a classic mopar, and if so do they want to share their experiences (in detail).

That's bull crap. To the poster go with it. If you can get all the pieces from a doner your worst hurdle is your fuel tank and pump. The rest is a cake walk.

I put a 5.9 from a 2001 Dodge Durango in my '68 Barracuda over the winter. I used a 1998 Ram 2500 5-speed ECM from Solo PCM's, Hotwire auto wiring harness, and an SCT Tuner from Hemifever. I love the EFI.
For the fuel system, I used the stock fuel tank with 3/8th's feed and return with a Surge tank system. It runs awesome even down below an 1/8 tank at the Willow Springs Road Course, and is cheaper than the custom tank with the ineffective baffles route.
With the wiring, computer and the fuel system handled, it was a simple swap that is WELL worth it.
It turned out that the 5.9 I got was a bit worn, as it puffs a bit of blue smoke from the passenger side exhaust on deceleration. I did change the cam, springs, timing set and resealed it.
Interestingly, it still gets better mileage than my slant 6 did and is a low 13 second car that's a ball to drive.
More upgrades to the motor and transmission are planned for later this year and next = 408 stroker with aluminum heads, overdrive auto and eventually a procharger kit.

How much $$$ would you estimate it took for the swap start to finish? 
Thanks.

2000 durango motor into a 65 coronet.
but aftermarket efi setup.
ran me 3k total from start to finish.
That is everything. nickle and dimed everything used to do it.
800 for the motor with accessories.
310 for the efi setup.
the rest goes into fuel pump, regulator, new gas tank, new pan and pickup, new radiator, fuel lines, new sending unit for the tank, flex plate for neutral balanced torque converter to 5.9, new motor mounts, extra nuts and bolts, rags, new lines for power steering pump and a/c, etc..
I mean that includes fuel to pick the stuff up, lunches while I was out getting it, etc.. the wife keeps track of every penny.
with a full donor, lots of these things wouldn't cost extra. but it does add up.

It wasn't cheap, but some of the costs were offset by the sale of my slant 6 and the fact that I got a long block for $400. I picked up a real nice rebuilt 727 & converter from the parts board here for $300, full new exhaust from Summit for under $400 delivered, Hotwire auto wiring harness & a rebuilt computer plus SCT Tuner with lifetime tunes, upgraded fuel system and on and on. I didn't want to add it up. I just buy parts as I need them, and have the extra money available. I also didn't go cheap on components and systems that I knew would have to support a supercharged stroker motor someday ie programmable ECM, fuel and cooling systems.

why would this be difficult?
I mounted a pump on the frame near the spring hanger. No big deal!

I'm glad this kind of stuff has been done before, successfully. I want to stay as stock as possible, mainly for the challenge of doing it as cheaply as possible with junkyard parts. (Mr. Ehrenberg, are you listening? THIS WOULD MAKE A GOOD SERIES OF ARTICLES!) What I'm envisioning is the engine with all the fuel injection parts, overdrive transmission, engine computer (separate transmission computer? I don't know), and harness from a single junked vehicle. As far as the fuel tank, pump, and return system, there I am open to customization. According to the Allpar web site, the Grand Cherokee went to returnless fuel injection in 1995, which might make it easier to adapt the fuel system of whatever car the drivetrain is going into. I don't know if that continued forever, or if it applied to Dodge trucks as well. Here's a link to the page on Allpar: http://www.allpar.com/SUVs/jeep/1993-grand-cherokee.htmlAlso according to Allpar, the Grand Cherokee went over to JTEC in 1996, so if there's a problem with JTEC, it might be avoidable by sticking to a pre-1996 drivetrain. I recently bought a 2003 Grand Cherokee with a blown engine and transplanted the entire drivetrain (4.7 V8 engine, transmission, and transfer case) from a wrecked 2001 Grand Cherokee into it. Both of them had the JTEC PCM, and I had no issues with the PCM not recognizing the different powertrain or anything, so JTEC has been kind to me, for what it's worth. (Ironically, my concern with that project was making sure I did get a car with JTEC and not the NGC, Next Generation Computer, PCM, which apparently some 03 Grand Cherokees did have. My 01 engine would not have worked with NGC because of having a different number of teeth on the cranskhaft and camshaft tone rings. Plus NGC had a combined PCM and transmission control module, so I might have had issues with the transmission as well.) Just to be clear, while I love carburetors and non-computer controlled drivetrains, the point of my future project is to get into some of these technical issues, figure them out, and beat them. This is the future. Also, at the risk of someone stealing my thunder, I think it would be really neat to do this with an early 80s Imperial, the ones where Chrysler tried (and failed) for the second time to do electronic fuel injection and ended up replacing it with a carbureted system for free. It would be a kind of vindication.

Last year i swapped a 97 obd2 5.9 w/fac efi and over drive trans in my 48 plym. Fuel delivery was a hurdle but not a big deal, inline efi pump w/a ls1 filter reg. Motor/trans was already retrofitted in a street rod before i got it so i didnt hafta sort a full wiring harness. It runs circles around the 355 that it replaced!  Just finished up a 01 5.9 carbed w/ airgap and edelbrock 600 in my 88 w250 pick up. Runs good but not as good as the 48? Both were supposed to be low mile motors. Efi in my opinion would be way to go

Seemed like I remembered they had an engineer in from Detroit fine tuning the thing? Sorry I don't remember more of it.
