I love how 20s is possible with a fullsize gas powered truck now adays! I was always a true believer of the gen III+ motors but until i got one i had no clue about the tuneability and power they can make and get such great fuel mileage under the right conditions! I am by no means a mpg freak lol dont get me wrong lol my 86 k10 got 9mpg with the old motor my car may get 12 but i beat on it reguarly with the 3500 verter. (Flame suit on) i had a 04 Dodge dakota 4x4 ext. Cab with the 4.7 v8 and it was a quick little truck but with intake and exhaust the best i ever got was 15mpg and that was highway!!! Averaged 9-11 in town it had 3.55 gears auto and 265/75/16 maxis big horns nothing crazy.to boot the motor only lasted till 40k the dodge bought me a new shortblock! then i knew the chevy gods were pissed that i went from a gm to a dodge!
