that's a cool story. I'm really surprised you had to jet down that much on the dommeys but 2300 feet what was the corrected. but 9375 work well with low signal at low rpm on heavy cars so that may make them work rich at lower flows since you had to of them for 2300 cfm???
I once read that the 9375's were greatr down low to get big cars moving but the annular boosters conversly ran leaner than others at high RPM's (high flow)???
