I get pretty good mileage
I went 300 miles - 2 weekends ago and use less then a half a tank
I felt that was pretty good
All highway
Cruise set right at 75
I did not check the MPG

I also have a 91 350 TBI 700r4 and have regularly knocked down
20 & 21 MPG - cruising at 72 mph
Lots on mods.

i have 4.10s in mine, and if i drive 75, then my rpm&#39;s are at about 2500... from what i remember and i get 19 mpg on the highway.

It&#39;s the 5.3 honestly it should have came with a 6.0 from the factory in the 4x4...it&#39;s just too small of a motor to move all that weight about.

But my current fuel economy isn&#39;t bad at all, 15.5-16.5 avg and nearly 20 straight freeway.

Yeah, I&#39;m trying to decide what mode to go.

6.0 HO heads with cam

Build a 9:1 comp 6.0 out of a core motor for cheap (stock crank and rods) then get a used ATI for it.

I just don&#39;t know which setup would be better
