One other quick comment too, Check your states emission laws. Most places wonÆt let you put an older engine in a newer rig, with out still passing the newer emission requirements.

And yeah, if you plan on throwing the additional power to the Jeep, you will need to change out the front and rear axles too, or at least you will need to after a few trips on the trails when you destroy both of your axles. The standard cut Dana 30 up front and the Dana 35 in the rear just arenÆt designed for a small block.

Basically the right way to do what you want to do is have a running ¢ or ¥ ton full size truck with a small block in it and swap the whole drive train into your jeep, which to me sounds like a waste to do with a new jeep even if it does have a 4 cyl in it, unless the current drive train in your jeep is already junk for some reason.
