I just made a trip to Aspen and back (from Denver) and was very pleased to see 15.3 mpg (corrected for tire size). Pretty good considering Loveland Pass, Fremont Pass, and of course... Independence Pass. I ran about 65mph indicated wherever possible.
setup: 202K on the bottom end, head reworked at 150k, carb'd by Jim C at the same time. 33/10.5 MT's, 3" lift, 4 speed, stock ratio, Yakima bars.
Now, if I could just break the 50mph barrier up to the Eisenhower
.
Maybe after the H55f, 4.11's and TBI? Though a Gen III vortec swap from Randy in Dallas is the goal.
