I can tell you from running 10 o2 sensors, fuel distribution moves around alot, based on RPM and load. I would look at the plugs and see if they are the same, if they are i wouldn't worry about it.

They burn darker than the others. #7 has always been a problem. If its a carb and the plugs are not real dark like black , and if the oil dosnt smell badly of gas I wouldn't be too concerned. Judging by the heads you are using this is a hot rod , not a mild build. If its a carb its just not a perfect system . If you smell the gas in the oil quickly after an oil change you should be concerned about cylinder wash down . Just my experience and observation.

I have dealt with this on 6bbl intakes. Not going to be WOT fuel issue. Idle/ part throttle and coasting. Fuel puddling on floor and running in wet. Small dam on runner floor fixed it for me. Didn't effect WOT in my experience.

Which version is your intake, early 440-3 (round individual injector bungs,, late 440-3 or 440-3X? They are all different under the carbs.

That is the later 440-3, not the early one with the cast in round bungs for tapping for EFI injectors. I'm sure it is not the taller bigger plenum 440-3X either.

The wilsons tapered 4 hole matched fairly well to the carb pad opening and I was following their direction with the removal of the clover leaf and putting their spacer on top. The straight 4 hole obviously covers more of the carb pad, so will see how this works out. May just be a common issue with this intake and I found it with the red dye in the fuel. Gonna call Brodix Monday and see what they say about a turtle in this intake just for curiosity.
