I have been running my Motorcraft for about a 2 years. It runs well and gets good mileage. The only remaining issue is hesistation off idle. It only does this in hi range, choke off and not every time, maybe 1/2 the time (makes me think I am close). I moved the accelerator pump linkage to the top hole for more pump/gas and it helped but did not eliminate it. I have wasted a couple cans of cleaner looking for vacuum leaks and never found one. I never notice it off road/low range. One thing I wondered if it has anything to do with the Offy intake (the one with water) as the Jeep had a non-functional Holley 4 barrel when I got it 3 years ago. Didn't know if the shear volume of this intake would makes some sort of difference. It would seem it would only pull into the engine what it pulled through the carb. Ideas of where to look next?
Anything is possible if you don't know what you are talking about.
