going from a 4 to a 6

[Gettin-Higher]

While I've done my share of engine work and rebuilds, I've not done a size swap. What's involved in taking my 89 YJ from a 4 to a 6?

See if I can't remember right.............

The motor mounts are different.
Everybody says it isn't worth the hassle.
Get the computer and wiring harness (I am assuming you are going 4.0) I believe it all just plugs in to the factory guages.
I don't know if the stock radiator from the 4 banger will work with the 6.
I have not done this swap, but looked into it before deciding a 5.0 swap was better for me. :D

Anyone else that can shed some light? I know some of you have done this, or have friends that have.

FYI...The radiator is the same for the 4 or 6 cyl.....I've heard from a lot of people that it's easier to swap in a small block rahter than a Jeep 6 cyl. I've nevr done it but I would make sure that you do your home work first.;) Good luck.
