" From: Jesse <j2sax@xxxxxxxxx> " " " I have an 87 4.0 o/d AT that seems like it would make " better power than the 258.... anyone ever run a 4.0 in " a full size? i haven't heard of one - so far... what gears are in that pig? the 4.0 doesn't like to lug like the 258, and you have the o/d to account for. you might want 3.73s or even 3.91s... for the first year or two, the zj [grand cherokee] 4.0 used aw4 autos, and i bet it weighs like a matador - what gears did they run? ________________________________________________________________________ Andrew Hay the genius nature internet rambler is to see what all have seen adh@xxxxxxxxxxxxxxxxx and think what none thought
