So the engine in my 1990 wrangler has gone over hill. The cylinders are scored and they are already bored .060 over. A good friend of mine has found a 1998 engine still assembled (it was removed because the owner put a bigger engine in). It also has the 5 speed transmission if I'm not mistaken the ax5 and transfer case with it. its quite a deal, but my question is would the block be able to fit in the 1990 wrangler? If I get parts for it would I need 1998?
