Re: 5.0 to 4.6 swap
Well . That 4.6 uses aode transmission among other differences . Gonna need wiring, brain, & not sure about motor mount points & trans mount stuff . Early 92 had aod that mounted to 4.6 & later style 92 tbey changed design of engine & trans . Sure others will answer also, but seems easier to find different 5.0L to put inor rebuild what you have with mods
