Hey, the answer is yes. measure the engine mounts to see how close they are in relation to each other. Because you are using a Chrysler engine, it MAY just bolt right in. But if it doesn't, don't panic, there is an adapter kit for just about any engine to put into a Jeep. Good luck.
P.S. don't forget to check the transmission bolt pattern also, you will most likly need an adapter for that as well.
