Were the 05' 4x4's substantially lighter than the 4G's?
if so, I suppose its possible with perfect DA on a cool day.
My 4G has 50hp more (at the crank) than the 3G Hemi
but at 5200lbs, my 10' RCSB 4x4 's best is 13.8/98.5 at over 2500' DA (13.4/101 DA corrected)
with just intake/exhaust/tune on 17's
