So I'm looking for a 99-04 Grand Cherokee, but I don't know which engine to go with. I want to go off-roading in it, so of course the v-8 would be better suited, but I want the reliability of the inline 6. Is the inline 6 still good for climbing? I'm also willing to put some money into the engine, but I'm not sure what to do to it. Any suggestions if I do end up getting the inline 6 on what to do to it? Or should I just go with the v-8? I'm also going to put a 4" lift on it with 31" or 33" tires. Thank you!
