What is the biggest engine that can fit in a jeep cherokee sport?

I have a 95, 4 door jeep cherokee sport with the 4.0 inline 6 engine in it currently. Ive started having problems with it and have realized if i want to keep the car i should change engines, also i want a flat new engine for it. i want a big engine in it cause i love mudding. my question is can i fit a hemi in it or no?|||It ain't worth it my friend, just stick to getting a new 4.0. The 4.0 I6 is a fantastic engine and would push many more horsepower if you get the right parts. Take the huge amount of money and time you will need to put a different engine in and invest it in a new 4.0 and aftermarket upgrades, you'll find you have saved a huge bundle of cash and months worth of painful work.





Good luck!|||Mmm, I have a 1991 Cherokee, and the engine has a HOLE in it, and I am not having any problems from it. Are you sure you need an engine swap?





Seriously, a 4.0 will easily last 200k miles or more.





The straight-six is an excellent choice for any kind of off-roading you may want to do.





Still, if you are insistent, I have heard of people getting good results from dropping a 350 into a Cherokee.





You might want to hit these guys up, I hear they do good work as far as getting different motors into vehicles.

Most of the transfer cases and differentials in those jeeps are barely suitable for handling the power of the 4.0 6 cylinder engine, and a V-8 will certainly show you the weakest link in the system. Good luck.|||you said the magic word; mudding. in that case, you can fit any motor you want. and when i say fit, i mean lots of pushing and shoving.


you can fit a 302 in there, its been done before. the problem is besides the transmission, is you have to change all your wiring as well.


its much cheaper and easier to try to get another 4.0 jeep motor. they have plenty of mudding power.|||You can fit a 350 in there but any V8 is going to put tremendous stress on the uni body frame rails. Your best bet is to think about taking that 4.0 and stroke it to a 4.6. This is accomplished by using a crank out of a 258. Talk to your local machine shop and see what they have to say about it. Get the whole engine balanced and it will scream.
