Body Damage is Cool

Do a little searching, here and with Google. Yes, it will fit, it's a great mod if you have the right casting number on the 4.0 head (some flow better than others). I did it on my 86 CJ and used my 4.2 intake and carb. Even without the MPI it made a huge difference for the better. Some waterjacket holes in the 4.0 head may have to be filled/plugged. There are plenty of online instructions on various methods. <img src="/forums/images/graemlins/cheers.gif" alt="" />
