Yes, the jeeps have the following choices factory, 199=3.75 bore and 3" stroke, 232=3.75" bore and 3.5" stroke, 242=3.88" bore and 3.42" stroke, 258=3.75" bore and 3.895" stroke, VAM 282=3.91" bore and 3.895" stroke. Mix and match the 4.0 block with any of these cranks and you could come up with several combos if you were willing to overcome the rod length issue.
