I have a chance at getting a fairly fresh 97 4.0L to replace my ailing 4.0L . What would it take to get it mated to the YJ? I don't believe it's a plug and play but for those that know - please share your thoughts.
OK. I will ask the stupid question...Why do you think it wont work? other than needing the pcm for the new motor, it should be a plug and play type of thing. Motor mounts are the same, bell housing is the same, heads are the same so therefore the manifolds will bolt on.
