Well right off the bat no. The 6cy mm's are in a different position on the frame. They have to sit farther up because of the longer engine. So you will have to change out the mounts completely.
Also I'm not completely sure, but I think you might have to retro-fit some things to go from FI to Carb. And do you have emissions testing where you live? If so then you won't be able to swap in an engine from an older year vehicle into a newer due to the differences in the emissions equipment.
