With the Ecoboost in the Bronco, Jeep needs to act now. That's way more engine than the Bronco needs.
Really don't need a V8. But if it fits, ok, why not. Oh, and you'll need a manual transmission option for it. .......actually screw that. Offer ONLY the manual trans with it. That way your killjoy dealers can't order them slushy. That would kill any other vehicle, but Jeepers are weird, and will go for it. They'll love it even more, with a pita clutch.
AEV's kit is great and all, I just forgot where I left my Rumpelstiltskin demon.
