I have always considered the V8 EFI more problematic in the long haul than straight carburation. The other problem
with the NAS V8 as I see it, is it's dependance on the ECU. Is it possible to convert the NAS to straight carburation such as the Weber 500 (as per RPI ), go to mallory distributor, retain the cats, and still pass emissions? Would love to get away from all this computer controlled cr*p that really shouldn't have a place in offroading IMO.
According to RPI, their 4.6 engine via Weber gets up to 23mpg, 30% power increase, instant throttle response, and no flat spots.. they also claim that the Weber 500 float positioning prevents stalling at extreme angles when offroading. What disadvantage would it be for NAS owners in the US?

Attaching 2 vacuum lines probably, one of which with a cheap thermo switch from NAPA.
