No tuning on the carb (modified GS455 Buick Stage-1) yet. Secondaries were running about 10% rich and the air valve wasn't opening soon enough so it would run perfect on the primaries, lean out at 3600RPM, and then start running rich at 4200RPM. I'll tweak that out once in the car though. Engine started to pull again at 6000RPM so I know there's more power available lower once the mixture is right.
