My 4.0 is running well so far. My question is when it’s time for a new engine can I put a carbureted 4.2 engine in it. In Mass the Jeep just has to pass safety. Thought it might be easier to work on a non computerized engine. My 89 YJ had some power. Is this a ridiculous swap or should I save up for a stroker engine which I heard is very expensive.
