Can't help you on the Dodge setup, anything can be made to work. You may end up spending a lot for sensors and such. Remember that you'll need a higher pressure electric fuel pump too.
GM TBI is probably easier. I bought the complete kit from Howell (www.howell-efi.com) about 5 years ago for $1250 to my door. It had everything but air cleaner and fuel lines (suggested but not required), and bolted on in an afternoon. It required an adapter for the TBI to 4BBL manifold (included), and they custom burn a PROM for the engine setup you have.
It started first try. It idles smoother, throttle response is crisper, mileage gained about 1 MPG, and it even runs upside down (don't ask how I know :mrgreen: ). It has performed perfectly for 5 years, with the exception of a bad O2 sensor. It passes emissions with flying colors. Best thing is, all parts are available at any parts store (although I've never needed any).
If you want to save money, Howell will sell you just the parts you want, and you can pull the rest at a boneyard. I'd suggest the wiring harness, PROM, and TBI adapter, then pull the TBI, computer, O2, temp, and MAP sensors from a 91-95 GM truck.
