In my opinion, the inline 6 is one of the best motors ever built. Bullet proof and dependable and plenty of power. No, never driven a 4cyl, I believe what you say, not debating that. Just stating that the 4.0 is a better motor IMO than the 4cyl. It might not be a rockstar compared to the 4, but I would rather have the 6 if I had a choice. I know your jeep came with the 4, so no choice in that, but wonder if your opinion would be the same if it was a 6? As for the v8 comment from bjeep, yeah, would love to have it!! But I do not have the skills, time or $ to do a swap like that. Would I if I could... more than likely, no. I am completely happy with my 6. My wheeling style fits it perfectly. It has power when I need it and I am not one to bounce the rev limiter much. I guess my point to this is, I think the majority of guys running a 6 are completely happy with it's performance and most have no plans on swapping one. Matt, I value your opinions on stuff like this and as I stated, I could be blown away if I drove yours around for a bit. But for me and my Jeep, we will have the 6 ;D
