I don't think mine's ever done better than that, but in 20 years I've never really checked it; I just make sure there's gas available every 100 miles if it's going that far. Mine's 438", 2x4 inline original carbs, 10.8:1, 260* @ .050, .565/.547 lift, 4-speed, 4.10, 27.5" tire, 3800 lbs, see Attachment. I generally keep it around 3000-3500 RPM but I have a rule that every time out, it sees full throttle at some point.

You guys will probably call me a liar but years ago when I move back here I drove my Hemi GTX back following my wife. She drove 55 to 60 and I never got out of the back 2 barrels. I got an honest 19mpg. I had a mild hydralic cam in it, quick advance curve in the distributer, 2" headers, 4-spd, 3.54 gears, and LR60-15's. That's the only time I ever drove it that nice, it about killed me. Dave

That really isn't as bad considering that I rarely get more than 12 mpg around town in my 4.6 thunderbird.
My wife has a 2005 T bird. REally bad on gas, unbelievable!

Haven't got the hemi done yet but the 440 in my 68 RR, auto, 3:91, bored 30 over, mild cam, 9:1 pistons, carter 750 gets about 14 at 70 mph.
I'm expecting 11 out of the hemi on the hiway
