HELP NEEDED!!! SEE BOTTOM OF POST IF YOU KNOW ANYTHING ABOUT THE V6 TRUCKS*
Ok It's been a long few weeks but the motor and trans are in the truck. Here are a few pictures.

I've done a whole lot of research on this particular swap and every thread that I have found has either claimed that it's been covered many times elsewhere, or merely states that it is possible. Well that first one sure as heck ain't true so I'll just go ahead and immortalize it here.
The Swap:
Starting with: 1988 PowerRam 50 4X4 Ext. Cab W/ 2.6L G54B and factory Auto trans. (Meaning that if you have any 2nd gen mighty max or Ram 50 with 4X4 this is applicable to your truck.)
This swap pertains to replacing the 2.6 with a 3.0L V6 (6G72 SOHC) out of a 1990 Mitsubishi Montero, and replacing the auto trans. with a 5 speed out of a V6 Dodge Raider (V5MT1-1)
More simply:
2.6L I4 (G54B) ---> 3.0L V6 (6G72 SOHC)
Auto Trans. (KM-148) ---> 5 speed Manual (V5MT1-1)
Pros:
-The Sticks (shifting levers that is) line up perfectly with the existing hole in the cab, and in my case only required a few cuts to make room for the transmission stick (I had an automatic). The transfer-case stick was fine.
-The motor mounts lined up perfectly and can even be bolted in. No need to make new ones.
-The ECU harness is (somewhat) separate from the main wiring harness and the ECU is located in the same place in the Montero as the "Carburetor Control Unit" is in the Ram
-Gobs of clearance on everything besides the oil pan and the brake lines.
-147hp NA and can be twin turboed for ~250hp with relative ease using factory Mitsubishi TD04 9Bs. (I got my twin turbos with intercoolers for $200)
-Pretty easy to do if you are willing to do a full drive-train swap in the first place.
-If you want to do a dash swap from a raider too (Highly recommended, they look sweet) You can take the whole harness and enjoy all of its cool features like cruise control, intermittent whipers, electric locks, and headlight sprayers (if you're into that).
-Pretty much turn-key after everything is reconnected (Shouldn't have any ECU troubles).
-You can contact me if you hit a roadblock and I'll try to help.
Cons:
-You will likely need a whole donor vehicle for the V6 to get all the appropriate parts. (try to get a 5 door Montero LS from '87-'90. They have all of the bells and whistles)
-The oil pan out of the Montero/Raider is completely incompatible with our trucks. The lowest part of the pan hits the front axle and differential within 4" of the motor mounts. You must buy or fabricate one for your truck.
-Not necessarily the most powerful swap when naturally aspirated (much better than the 2.6 though)
-Want to upgrade the ECU or anything at all in the motor? I hope you can tune your own ECU and fabricate precision parts because that's all you can do (besides pay a bunch of money to have a shop do it for you)...
-The transmission crossmember has to be modified (not extensively though).
-The shifter from the Raider is at an uncomfortable distance from the seat if you like to lean back. Try to find a factory one for the Ram/mighty max.
-You need to make new driveshafts
-If you want to turbo it you can't just buy turbo headers or down pipes. You must make them.
-The V6 radiator hits the factory power steering lines so they must be (slightly) rerouted.
-The brake lines from the booster are uncomfortably close to the driver side manifold and should probably be rerouted. See for yourself:

-The battery in the Montero is in the opposite corner as the one in the ram, so modification to the wiring harness is needed (to extend it to the front drivers corner that is. You can't just move the battery to the same place as the Montero's as the location is too shallow for it.).
-Fuel lines need to be rerouted in the engine bay, and the stock fuel pump is inadequate for the V6.
-Obtaining the clutch pedal and linkage is all but impossible unless your junkyard has a miraculously un-crushed manual 2nd gen.
*Regrading the Oil pan.
I just ordered this oil pan from Orielly's:
Pan bottom.jpgPan left.jpgPan right.jpgPan top.jpg
Does it look anything like the V6 Ram 50 Pan? More specifically, Does that pan look like it will fit around the front axle/pumpkin?
I could really use the help. Thanks in advance.
