Having spent a good bit of time reading everything I can find here about the single carb set up about the only thing I'm having trouble wrapping my mind around is the need to have all the runners exactly the same length. Taken to an extreme, the intake runners on my Chrysler slant 6 were a study in "how different can we make them" and except for cold weather starting (below -35F forget it) they worked fine. Has anyone actually played with this and found a real difference?
