Factory 318 EFI in a Dakota - mo power?

1st thing I would do is put a true duel exhaust on it,not a cat system,you can get a obd2 catalatic dual in dual out,think mine came 2 1/4'' but had muffler shop open it to 2 1/2'',,run 2 1/2'' pipes and retain your sensors,I ran headers also,think we ran some type of glasspak mufflers,also had a hypertech programer[3stage],you could also rework the throttle body to a larger size like from a 48 mm to a 52mm or something like that,its been a few yrs since I did it so may not be accurate or exact,a limited slip[sure grip] in the rear makes a difference in putting the power to the asphalt..and 1 more thing is after we did all the above which indeed helped alot we installed under the throttle body a little device known as the 'tornado' and that 1 thing was more noticable in the seat of the pants improvement and throttle response and we gained 2-3 mpg's...all this can be done without getting into the engine and between the muffler shop and your garage you can do it all yourself,next step would prob be a nitrous plate 100-200 shot[all this was done on a 98 RT dak 360]
