I got 20mpg on a real mellow run (flat) to a junk yard (50-55mph) with a Carter 500cfm that I did a whole lot of tuning, as well as valve lash and ignition in my 64 PWTW (5k#, 4.10 gears, no OD). Mostly stock with a Weiand 4bbl manifold, dual exhaust, 2" with glass packs. Have done 13mpg before all the tuning in the mountains on 400mi. trips going over 11,500ft. passes. I have a new 600cfm Holley that I have not tried yet. It will also do 100mph! Don't try to stop though.
