I don't think the new pick ups with the 5.3's and new 5 speed's hit 25 MPG... how on Earth could a less aerodynamic, heavier pick up do that?

I don't think the old trucks are heavier than the new ones; our 2002 GMT800 is quite a bit heavier than our previous trucks -

Yea I just dropped a used 87 tbi 350 in my 84 and slapped a carb on it and it surprises me how quick it is even with 2.73's. Its will burn the right rear clean off the rim almost to 3rd gear if you don't let up....From a straight standing stop, hell you can't even try and make a right turn into traffic in a hurry cause it will just spin and you don't go anywhere..lol

Ive heard of this before. 305 2.73 rear end with the dodge 5 speed trans and the first attempt at electronic spark controll. Under perfect conditions its possible just not likely.
