My '84 D100 gets 20mpg at 65mph. 225, 833od, 3.91sg, 235x15 tire

My '68 V200 gets 25mpg at 65mph. 225, 904, 2.94peg, 185x13 tire

My sister bought a loaded '80 Mirada new, even had the am/fm/cb/cassette radio, 225, 904, 2.45, 215x14 tire, it got 23mpg at 70mph.

There's something wrong with a slant six A body that gets less than 20mpg/hwy.
