Using Fuel A plus Fuel B and the shown A/F ratio we 2036.9 lbs/hr Air or roughly 445 SCFM
Using 181.95 Un Corrected HP and Fuel A we get a BSFC of 1.14097
Using Fuel A and the shown A/F ratio we 1712.7 lbs/hr Air or roughly 374 SCFM
I get a 1.053 Correction Factor

Thanks for doing the thinking, {math} for me. Made some sense out of that mess. I am a little puzzled by that fuel B. It should be zero and blocked off 100%. A Q-jet only has one inlet/fuel bowl. Certainly has some problems there. Some dyno, some carburetor, some engine? I think it's all because it's a Pontiac!!
