Did you have Keith Dyno your motor? I just installed a KC 496 and it has a Quickfuel 850 double pumper. My motor made 681HP at 6700 at the crank and the air fuel was between 12.5 and 13.0. We dynoed it yesterday on a chassic dyno and the air fuel with the headers and pipes etc never went above 12.5. I wouldn't run your motor above 13 much as that's getting pretty lean. Call Keith as he is an expert at these FEs...
