wot on an n/a engine should be between 12.8 and 13.3. 14.7 is nominal stoichiometry for emissions and effciency, as well as a steady cruise.

and as far as stall speed, the test i mentioned before is the breakaway. the stall speed should be 200-400 rpm higher than the breakaway. i.e. if it revs to 1800 before it starts to move with the brakes applied, the approximate stall speed is 2000-2200.

 

thanks for the info . i wasn't sure whaty the a/f should be in these cars at wot .i will be running a wideband when i drop a new motor in mine this summer
