Our  Corvairs, for example, can run with LEANER than stoichiometric (about 
14.7:1  A/F ratio) which the narrow band O2 sensors lock the computer 
control in for  cruising on the newer cars.  Our Corvairs can run leaner than that 
for  higher gas mileage cruising if we use electronic fuel injection and a 
WIDE  band O2 sensor to control it.  


Frank,
Maybe so, but according to the only real data we have, the official  
Corvair/Chev engine test reports, stock Corvairs NEVER ever got close to Stoich.  
Apparently the engineers were so afraid of possible preignition and/or  
detonation that they saw to it (according to the data) that no Corvair engine  
ever ran lean. To run a Corvair as lean as you are suggesting would seem to 
be  inviting problems if one is to accept the test data in these reports.
