got a '87 4.0 that I have removed from my '87. I bought the vehicle new and have taken excellent care of it. The engine has had mobile 1 synthetic since 2500 miles. runs great no leaks or oil consumption. Engine has 150k on it. I also have the aw4, engine/computer harness, stock computer and trans controler. Give me a shout, im in Georgia... if you want you can call me @ 678-617-6486 for better details... Oh, the reason I removed the engine etc is to upgrade to a LT1.
Bruce, I am in the process of buying an XJ to part out. I'm not sure of the year but I'll let you know as soon as I get it. I do know the 4.0 in it runs well. Chris.
