My LQ9 in '71 K5 with 4"lift, 35" MTs, 4L60e, 4.10 gears, no top and a medium foot gets about 10.5mpg overall. Local with some highway driving. That was 1-2 months after the rebuild...I haven't checked it lately but I doubt it's changed much.

It's too easy to get on the gas because it moves and sounds good!
