Ok the 6cyl engine should be the 4.2l 258, and it goes all the way up to 90' so i am for sure that it is, if you wanna double check it like i did go here www.quadratec.com
then go to jeep, performance, search entire catalog type in Engine and it will show you exactly, the engine block itself sells for 1,800 THE ENGINE IS ON PAGE 8 OF 13
Slow steady project.
