97 B4000 Engine Swap?
 

I was just hoping that someone could tell me (and I'm sure there is someone on here who can answer my question), could I swap the V6 engine that's in my 97 B4000 with a 4cyl engine? I would just like to know for the future. Eventually I'd like to put in a 4cyl engine to make the truck more of a gas saver. I mean I like the truck so I'd like to keep it and replace the engine some day with a newer 4cyl engine.

Any answers appreciated, thanks.
