Ok So what you ahve now is a modern town car! It is computerized and all the parts work together.
In order to put a V-8 in there you will need the engine, tranny, transfer case, rear end and all the brackets and parts mounted on the engine.
Now you will have to install motor mounts, tranny-transfer case mounts and cross members under the Jeep to make all that fit the frame.
THEN you will have to have driveshafts made to fit! Ok so now it is in there...now NONE of the guages will work! So extensive parts swapping will have to be done to get them to work.
Now you will have to have ALL the exhaust system made new to fit. I havn't started to talk about the brake system yet have I?
So now you have more money spent than trading for a rubicon would cost you! And the vehicle you are riding will be behind a rubicon ANYWHERE YOU GO!
Oh yeah, you have not said where you are located have you? If you have vehicle inspections where ever that is... you just may not be able to get that thing inspected ever again!
