Only way I know is check the casting numbers on the block. To get more info go to They have almost every bit of info on any Chrysler product ever made, including Jeep.

Driver's side of the engine block, towards the back, there should be either a 318 or a 360 cast into it.

Check the diameter of the front or rear seals - shoot measure the width of the round indent on the end of the oil pan.
