15.0 mpg to 21.6 mpg!
I don't think my engine would idle AT ALL at 14.7 AFR. And when I ignore that AFR gauge and set idle based on the Edelbrock manual, I wind up in the 13.0 range anyway.
WOT
12.8:1 - Lean best torque
12.2:1 - Mean best torque
11.76:1 - Rich best torque
11.01:1 - Fastest flame speed in cylinder
Right out of the Edelbrock carb manual below. The table below compared with the numbers above is what I'm shooting for.
