wifes waggy (89, with a reman engine i got in a 82 parts wag) with 31's (bfg a/t) and 2.72's gets 14 pretty regularly with a q-jet. nearly 15 when it is hot outside (much less time on the choke)

There is no way to rule innocent men.
The only power government has is the power to crack down on criminals.
Well, when there aren't enough criminals, one makes them.
One declares so many things to be a crime that it becomes impossible for men to live without breaking laws.

Quite possible. I got 14.5 to 15.2 with my 87GW - 360, 210K miles, 31's, edel intake, better cam, edel headers, edel 1405 4b carb, upgraded ignition and keeping my foot off the skinny pedal. With all that aside I got 12 average.

I can't get out of the 10-11 range, but mine is a Full time. It runs excellent, and the plugs almost look like it runs too lean. Maybe I should just do the cam, intake and carb swap. Everybody seems to get better mileage, as long as they stay out of the throttle.

Just got home from a 325 mile round trip to my gunsmiths place. I-80/90 most of the way about 20 miles of 2 lane at each end both ways. holding about 70-75 mph on the Toll Rds (had to keep out of the trucker's way). I filled up before I left, when I got there, and when I got back home. just calculated the mileage @ 15.7 .
Its all stock except for the ignition improvements--87GW 360 auto. Its going in for the Edlebrock manifold and 1406 transplant, finish the desmogging and replace/renew all vacuum stuff on Thursday. I may never see that mileage again.
