Got a '86 MJ with a busted 2.8.,,,, Waiting for the gasps of surprise to die down,,,,,,. In looking for an engine to swap I found there is oodles of swaps and info for the 3.4. I also noticed there is a 3.1 which seems to be a much better engine and should be easier to find as there were more of them made. But there is almost nothing on it about swapping or anything else. I am looking for any oplnlons any one may have on these ,3.1, engines before I spring a couple bucks and get one. I am planning on getting a complete donor so I can swap everything over and have multi port injection. Any thoughts, hints, opinions greatly appreciated. Jim
