Hey, if you are going to put a V8 on a JK, it will be better if you find a 70-72 V8 totally rusted CJ5, and find a JK 2dr with a blown motor/trany or flooded, and throw the JK body on top of the Awesome older CJ5 chassis and tough suspension !!!!!!! It will be easier, cheaper, and in the long run, you will end up with an AWESOME JK !!!!!!
