[AT] AT Digest, Vol 39, Issue 6 cylinder Chevrolet

[Larry D Goss]

The article from "Look" magazine is not mentioned here.  It probably has 
been dismissed because it was about maximizing mileage by using special 
driving conditions rather than during everyday driving.  If I remember 
correctly, there were only a couple of stretches on the track were the car 
got to the speed range of 30 to 40 mph, and the engine was not running all 
the time during the test.  Restarting the engine was done solely by putting 
the transmission in third gear and letting out on the clutch.
