As far as the conversion goes, its pretty straight forward I think, you will have to ditch alot of the electronics from the 350 motor, It will bolt in with the exception of one of the engine shock mounts, (it will be on the wrong side for your 84 300 sd. If you swap engine and trans together it will work ok.

Problem could arrive when emissions finds out you put an older engine into a newer car, however if that is not a concern, the actually time to do the sway should be about a weekend.


you shouldnt run into many issue, since you have both cars.
