Air Fuel Ratio?

[crazyshopmonkey]

I have the FAST Wide Band Air/Fuel Ratio Analog Gauge in my ride and I just added Aluminum heads and a Compu-tronix distributorless ignition, just curious whats a good Air/Fuel Ratio to run on a 1968 small block camaro or just get some basic starting points on some settings from someone with experience with these

I recently purchased the FAST dual A/F metering system for my car and had the exact same question and found the following links very useful:

You can easily run your car at 13.5 everywhere and 12.8 at WOT. This is not "ideal" but it will run well enough tho tune it. You can than try leaner mixtures under light loads and cruze conditions, say 14- 14.5. Dont fall into the 14.7 trap you will pull your hair out . These ratios may be possible and sometimes leaner 15:1 ratios are achievable. Let me know how it goes and good luck
