84 Grand Wagoneer Engine Swap

I would like to swap a Mopar 360 Magnum for my AMC 360. I have a 84 Grand Wagoneer. Does anyone make the adapters to do this swap? I have seen Guys stuff all sorts of engines into different vehicles in the four wheel magazines and thought maybe I could do it too. I really don't mind if I have to swap transmission, transfer case etc. My overall goal is to have a fuel injected engine with enough power for towing and off-roading. Should I keep my AMC 360 and swap out the intake and bolt on a projection kit? Any input is welcomed as I am new to the FSJ world.

well if ur ok with wasting ur current eng and trany, then id say do so and go total GM. gotta find a wrecked injected donor tho...or just any carb GM v8/AT and install EFI on it. check with smog laws, if any, on what swaps r legal in the first place.

If you can afford it, the Magnum engine works great, can be smog legal in the Peoples' Republic of CA and would make more power without loss of mileage over the AMC 360. The Howell 360 efi kit is easy to install on the original 360 as is the Holly kit, but I don't think they are smog legal yet. If you use a Magnum engine, the 93-95 EFI setup is easier to adapt to an older vehicle. Be aware that there are no kits or aftermarket wire harnesses like the bellybutton brands have available, so it is a make-it-yourself proposition all the way. I put a '95 Dakota EFI/ZJ engine and NV3500 5 speed trans in my CJ8, and I don't regret it one bit. The mounts weren't too hard to make but the wiring would be a bear for a non-Chrysler/Jeep tech to adapt. Hope this helps, good luck!

I have taken the throttle body EFI from an 89 Chevy truck and installed it as is on My 1980 jeep Grand wagoneer....it works like a champ. there are some issues:

1. Buy a complete GM TBI system including throttle body, computer wiring harness and all sensors, AND the GM ignition system including coil and the parts in the distributor. I suggest you look at a wiring diagram before you go to the junkyard BEFORE you go to buy, so you know everything you need. Total cost $250 MAX

2. You need to buy an external fuel pump and adapter to bolt the throttle body to the factory manifold. total $150 from Holley part #'s 512-103 and 17-47. I also recommend the Holley wires # 50-9804 AND changing the distributor cap to a IH Scout cap, (same cap but with male posts) about $80

3. You have to dsconnect the vacuum advance as the Chevy computer ignition does the advance electronically.

4. You have to mount the ignition parts that GM puts in the distributor remotely and wire back to the distruibutor, etc.

5. Start the timing about 15º advanced.

6. I also connected a fuel/air guage and the GM computer plug in the glove compartment.

Anyway I have been driving it for 3 or 4 months..and it is wonderful. The GM system cannot tell the difference between a chevy 350 and an AMC 360. They are both Heat pumps that work within the same control parameters.

good luck

When you put the Chevy EFI system on the AMC 360, did you use the stock two barrel intake? or other?

Can you recommend a web link to get an easy copy of the needed wiring diagram to make sure I rob all of the needed parts?

Thanks for any help.
