Webers and an A/F Ratio setup
I was playing with an Air / Fuel Ratio meter on my 347 with Webers. I put the Oxygen Sensor about a foot from the header flange in the 3" collector of the ERA system. Testing resulted in a change to the idle jet from a 65 to a 60 and a pretty flat 14.6 fuel curve. It runs really good now. The car likes no filters and open pipes.
On the dyno you can see the accelerator pump contribution.
