Ok I blew the motor up in my 97 xj trail rig (4.0) a good friend of mine found a cheap complete 99 4.0 out of another XJ. With a spun rod bearing. I have a 4.2 crank from a 76 CJ. I am planing on getting 4.2 rods and putting the stock 4.0 pistons on them and using the 4.2 crank. Ill be replacing all of the bearing and seals and I have 8.5mm wires, msd coil, lt1 injectors, 99 intake manifold, apn header, and if I have the time and money I am going to gasket match the head and have my throttle body bored. Ill be using the stock cam but I'm replacing the timing set since ill have the motor out. Is there anything else I need to do to make it run right? Deck the block? Thicker head gasket?
