i think you need a new intake manifold
and you could see waht happens if you jsut chop off the wires for the engine and jsut run the wires to the tranny, you would be running with a check engine light on all the time, but it might work

I think the 94 was still the RH tranny. The OD switch does run through the PCM, but that is the only tranny control for the PCM. I think they went to the RE tranny in 95 or 96. Not positive on that.
If you go carb you will need a new harness. The PCM will obviously be useless. I also think all the gauges run through the PCM, so you will lose those. The fuel system will also need to be addressed. I think a carb runs at much lower fuel pressure than the MPI setup. There may be some other odds and ends as well. I know many have gone to a carb or swapped to an old big block.

i think its a stupid idea. you will ruin a good running, reliable truck. it will take forever to get everything working right,(o/d). not worth it what so ever. i dont even think putting a carb on it would give it more power. less i believe. look at the old LA style engines. a 1985 carbed 318 only had 170 hp 260 tq, and the magnum 318 of any year had 230hp and 295tq. be smart.

I carbed my '94. I changed: Intake,Distributor, Ignition system, Guages, Fuel pump.I wired the OD direct with an on-off switch. The computer controls the OD with a speed sensor and gear shft position. Without the computer, you have to manualy control when the OD is active. If you don't disengage it, you could have OD in first or second gear. I put a micro switch on the shifter that disengages the OD when the shifter is taken out of third gear. I don't have a lockup converter. Dan

Just put one of those Mopar Performance four barrel throttle bodies on an M1 intake that has the injector bosses on it. Then upgrade to high out put injectors. Long tube headers make a big differance also. The four barrel TB costs around $500.00,M1 about $300.00, but that would be less than screwing around with a carb and everything you would have to do to get it to work correctly. Dan

The power difference has more to do with the cam/heads and smog era devices. Look at the mopar magnum crate engines, they advertise the same power either MPI or Carb'd.

in other words, completely pointless to ruin a perfectly good running truck, just to turn it into a piece of sh!t.

I do not know the reasons that he is considering the switch to a carb/non computer controlled ignition but I am to looking very hard at this swap option myself to just get my '94 5.2 Dakota to run right without the bucking/ missing issues. I have spent a ton of money trying to get the truck to run correctly with the original set-up to no avail up to now. I have gotten tired of spending money with maybe this will work and still ending up with the EXACT same problem that surfaced soon after I bought the truck about 4 years ago. At least going this route I could be assured that my trucks engine would cruise smoothly and happily down the highway regardless of whether it is light or heavy acceleration. I to would be very appreciative if the Dakota guru's here on this board could tell me what functions I would lose by bypassing the ecm for fuel and ignition issues and the best way to restore the lost functions that do occur. As far as the fuel pressure issue that should be able to be taken care of easily enough with a good quality regulator wih a return line to the fuel tank. I really like my truck when it runs right and I am planning on keeping it for quite a few years so going back to old school simple does not sound like such a bad idea to me from the aspect of shadetree diagnostics in itself. All the new computer controlled aspects are nice when they work right but they sure make the dealers and the shops happy when they don't and nobody can figure out what the problem is!
