Single Carb or Dual Quads which is better?

[Excaliber]

I was running mechanical secondaries with a pair of 600 cfm 'center squirters', which are basically 'drag race' carbs, not even a power valve on them! I did like the 'instant kick' they provided when you mashed the gas (this assumes all the planet were lined up, the atmospheric conditions were perfect and Jupiter also aligned with Mars). When they were working man it was great (mpg was horrible, by the way). I swapped them out for vacuum secondaries, same size, smaller jets with a power valve. I DID feel the loss of 'kick' when you mashed the gas hard, BUT, 1/4 mile times were virtually the same (as measured to the hundredths of a second)! They were also more reliable, but then again, those center squirters were old and finicky on the best of days.
