I think the 5.9 was the fastest production SUV until the 6.1L SRT8 came out! The unibodies are just so god damn light! Did you paint the trim, looks really nice.
IMO cherokees, Grands and wagoneers are the ultimate sleepers. I wouldnt say mine is a sleeper because it has a fairly high lift, but in general, people are surprised when the see a built "station wagon" haha. I mean the ratio of stock cherokees to built ones is low. And if you see a wrangler you immediately think off road, not so with the wagons.
There was a SWEET Grand wagoneer in JP that this guy in south america owned, think it had like 33's on the stock wheels, and either a built 360 or some FI V8.
