I have an 03 Jeep Grand Cherokee Laredo 4.0 with a blown motor and yes I mean blown it has a hole in the side of the block but I also have a motor mainly the block from a 97 Grand Cherokee Laredo they are both 4.0 my question is can I take the block from the 97 and put it in the 03 will everything line up need to know ASAP as I am down a vehicle and if so will the camshaft sensor in the little weird looking key thing that goes in place of the distributor work on the 97 engine or would I have to keep it distributor don't mind either way just would prefer coil pack
