One more thing, what purpose does the balance Tube actually serve?
Is it for idle quality, to help "balance" the carbs someway for some purpose, it a "softener" for intake pulses to help the carb, does air flow much in the tube, can it be replaced by a #12AN hose, etc?
My thinking, for an EFI sequential port injection Long ram, it ain't needed.
Well? shock

Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.
