3.9 V8 running a little rough - thread recommendations

anyone out there maybe could give me some ideas of search threads for this?
i have an 85' 110 thats got a 3.9 donor ('95 disco).
the exhaust was left on from the 3.5 making it a little tougher for it to breathe, but i don't think that's the cause of this...
its a manual, and when i shift gears the engine constantly sounds like i'm shifting too early, even when i wind the gears out a bit. (no tach, but positive i'm somewhere close to the 4000 range)
so when i'm in 5th doing 60 and put the pedal down it sounds like i'm throwing too much fuel at the engine.....also for example when i'm in 3rd doing 40 and drop it into 4th.
i apologize for not having a better description.
any thoughts? would this have anything to do with the distributor or fuel injection?
if you live in the seattle area i'd be more than happy to take you for a spin to get a beer so you could hear it firsthand. i'll throw in a second beer if you can tell me how to get it running better.
thanks for any input, er......any helpful input. (i.e. - no i can't afford a 200tdi to put in its place )
