Hah! mannydantyla, I admire your energy! but when it comes to our Cherokees, slipstream mods are just "polishing a turd." They're boxy, blocky and tall. Just use good lubricants and keep clean and tuned in all respects and enjoy 22 - 24 MPG (with AX-15 manual trans) and call it good. Your kammback for the Cherokee made me smile, though. Next: Kammback on an ox cart? ;^)
