Clearly you've never driven a jeep with a V8. I have and I've rode in others. It should have come like that from the factory. The factory motors just don't have the power for 40's and one ton axles.
You're supposed to be the resident smartass... I figured at least you would know when someone's busting balls!
On a serious note, yes I have ridden in (and driven) v8 jeeps. A friend of mine was doing hemi swaps back in the day at a dealership across town and I was able to try a couple out. Yes they are fun, yes they are more powerful, I'm not knocking them in any way and more power to those that have them.
I will say that diesel is the future and you might want to embrace this because it's coming and once they are here you will wonder why you ever questioned them. Just to preface this so you don't think I'm biased... I love v8's and I love power. I'm currently building a one off coyote foxbody turbo that will be capable of 1000hp so I get it.
Having said that a diesel is a better option for the jeep in almost every way which is why Chrysler is going to eventually put them in wranglers and not v8's. By the way wranglers overseas already have them! They get better fuel economy. Wranglers in Europe w/diesels get almost 30mpg. They are lighter which has obvious benefits for off roading. They make gobs of torque, something that someone with big tires would appreciate. Lastly, modding them results in much bigger gains in usable areas than gas. Ever driven a 1ton diesel with 1000 ft/lbs? If you would have you'd know.
I understand it's not familiar just like 4door jk's weren't when they came out but look at them now. All I'm saying is to have an open mind because contrary to what "you" think... Chrysler will never make a v8 wrangler, it's not gonna happen.
To the OP, my advice would be to wait on the diesel swap. Although unconfirmed, its a very good chance that Chrysler will release a diesel wrangler in America in 2018. I would just buy one then and save yourself a bunch of money. Good luck!
