The balance tube or crossover pipe needs to be placed properly.Usually just behind the header collector outlet.You want it close to the hot spot.This works on exahust pulsing and can add on a ford 289 a few extra HP.I was told by the shop that built my engines maybe as much as 7 to 10 HP
This shop was a noted builder of race engines.
