If someone is looking for a complete motor with Borla header for swap in CJ,YJ, XJ or early TJ. It's all there including wiring and PCM. Just let me know if you have any questions. It would be best to call me (228)806-7418. 93' 4.0L block,4.2L big crank. Special pistons dished to reduce compression. (Runs on cheap gas with no ping.) 24lbs ford injectors. I have all the specs on this motor. Used it on a trail rig for about 2 years (less than 1,000 miles). This is a great engine. Located in South MS. $1,200.
