[QUOTE="cribbj, post: 462570, member: 25798"] Supposedly it was "gone through" by the seller who is a well known Jeep specialist in Houston, and who knew we were embarking on a very long road trip. I've always believed that taller tires lower engine RPM, all other things being equal, and give better gas mileage, so it must be the gearing that is responsible for the horrible MPG. And I agree, this 3.8 engine is sooooo underpowered. The Chevy engine & tranny swap suggested by BlackJKU sounds like the most reasonable way forward.... That or 5 gals of gas & a match.... I'll be doing some research in the "Builds" section of this forum. But why Chevy engine/tranny? Why not stay Mopar and use a 5.7 Hemi or similar? Is the Chevy swap that much easier/cost effective?
