Has this engine been running with an existing BIN or are you just beginning? If the latter, the BIN Dave provided is a good starting point. Spark may be a bit high for those heads and CR, but easily adjustable once running. Another thing noticed are the injectors at 32#. Injectors of that size on a modded 350 will likely result in an extremely rich idle as well as rich above-idle. Take a look at this as it explains the issue and provides some recommendations: http://gearhead-efi.com/Fuel-Injecti...oltage-Offsets
