Hello all, I am a newbie here. I have a '04 rubicon and will be doing a V8 conversion, just not sure which motor I want to go with yet. I have it narrowed down, but im going to stay open minded as well. This will be my daily driver which the whole reason for my question so I will get to it now... I know there are tons of threads about V8 conversions, but I can not find anything about the gas mileage from people who have completed it. I was looking for some numbers from people that had the conversion already and not just estimates. Info on any V8's (preferably 5.0L up with 300+rwhp and tq) as well as the gears you are running with that would be greatly appretiated.
