Edelbrock LD340 WTH?!?!?

Ok so today I did a little research on small block intakes, the famed LD340 to be exact. What's so special about them and why they supposedly out perform all others?
This is what I found, look at the runner design, the LD340 runners are at the opposing ports. They hit on all the opposite cylinders as all the others. Could that have been Vic Edelbrocks secret with the LD340? The intake port pulses are better that way? Why don't the others all try this to see what happens? I checked other manifolds and all are different from the LD340.
