whats your average miles per gallon achieved with your 199 or 232 I6? I haven't been driving mine long..and I drive it a little hard but the MPG seems too low and I'd like to compare. I think I'm getting about 12mpg..that included a 15mile road race with a 74 cutlass so normally prob about 13-14mpg. thanks >
Woah! You should be getting 16-18mpg average combined mileage, unless your axle ratio is something crazy. With an axle around 3:1, at a steady 60 - 65 mph in a sedan or even a wagon with one or two people and not a ton of bricks, 17 - 19 mpg. Some people get higher peak mileage, but I tend to do 1000 mile averages (the beauty of spreadsheets).
I'm getting an easy 21 mpg in my 258-powered Hornet (average over 1000 miles), combined city/highway, mostly highway though, and on the highway I drive 65-75 and I'm not easy on the throttle in this car. Mine's an automatic, 2.73:1 axle, small Weber carb, decent exhaust but otherwise 100% dead stock. Engine is pretty fresh though (bought rebuilt long block from a friend.)
(I have every single fuel fillup and mileage measure on my 1963 Rambler dating back to 1994, many with notes on tuneup, timing changes, etc. Missed a few here and there, but not many. It's
