[QUOTE="dodgerammit, post: 441014, member: 21375"] Personally, I like having a 4.0 in a Wrangler, but having ran LS vehicles for almost 15 years, you won't be disappointed with that 5.3 in anything. There's a reason my Wagoneer now has a gen 3 truck motor in it. I'd wager you get better fuel economy than the 4.0 as well. I'd recommend gearing the axles something like 3.73 or lower and utilizing an OD trans for full potential of performance and economy. That said, the 4.8 in the Wag does fine and cruises at interstate speeds with the 727 and 2.72s. [/QUOTE]
