4.0 swap worth it?

i desperately need more power, and i was wondering if ditching the little 2.5 4cyl for the 4.0 I6 would be worth it. i really want to keep my manual tranny, and i dont want to have to change to much.

right now im running 35s with 4.88s and i cant even make it up novice hills without 4low. now when it comes to the real climbs, its no problem bc i have the klune-v and tera 2 low kit, but i dont want to use them for every hill i come up on. and the same with mud holes, i bog down in any decent hole. i have to rev it up and dump the clutch to get through, its killing my clutch .

so what do you think?

I highly suggest if you have your heart set on the 4.0, that you sell your Jeep and get another one that has it. The changeover is a major undertaking and would expensive.

Better to go with a 350 if you want to change out the motor.

i dont have my heart set on the 4.0, i just thought that it would have been the easiest route. i would much rather have a 350 in there, but im affraid of all the weight and my front end sagging down.

that, and i have WAY too much in my jeep to get rid of it ha

your manual tranny won't last behind a I6. It doesn't really last behind the 4 cylinder. I agree if you are set on a motor swap go V8 the first time and get it done. The weight of a TBI 350 isn't much more than the I6. It is pretty easy to upgrade springs for the 350 swap.

if i went with a v8, it would most likely be the ls1, and id probably go with the 4l60e. what would i have to do to keep my klune-v?
