Another Jeep. The 4.0 also fits easily into many old AMC's that had the AMC I6 as a possibility (the 4.0 really just is an advanced AMC I6). Beyond that, I'm not sure what else. I've been entertaining the thought of putting my 96's 4.0 into a Gremlin that needs an engine for the girlfriend (LOVES Gremlins), but finding a solid Gremlin is pretty hard.

My 96 XJ will be for sale soon. I haven't prepared an ad for it yet, but the most current info regarding its status can be found HERE
