air/fuel ratio

Any one know what the stock air/fuel ratio on a '98 Cobra is? I am currently at 10:1 to 11:1 through the rpm range. Looks very rich to me. Thanks.

That is WAY rich. Usually stock is 12:1 or leaner. Max power is generally between 12.8:1 and 13.2:1 on a N/A car.

Thanks Chris. I figured it was around 12 or leaner. Just put a chip on it to lean the mixture some and bump timing. Going to the dyno Thursday to see what the results are. Thanks again.
