First question, I have heard that the Grand Cherokee 4.0`s had different blocks (mounting lugs for the accessories) than a XJ 4.0 block. Any one know what year blocks will interchange with what? I know the heads are different and can be interchanged with a adapter plate.
Second question, I have a 96 XJ block I want to rebuild and put in my 2000 XJ the head is already on the 2000 from the 96. They look the same to me however I have a guy telling me no way.
