Which is faster carb or Fuel injection?

[Tony Curcio]

I'm gonna take a stab at this. The Third Gen Camaros mentioned above have a manifold with relatively long runners, which will make more power down low, and perhaps explains why you observed a harder launch.
Q-Jet manifold that I assume Frank and Lee refer to have much shorter runners, and should make peak power at a higher RPM, which probably accounts for the higher peak HP observed.
If the comparison was made with identical manifolds and the same total area throttle body/throttle blades, and fuel curves both optimized to whatever extent possible, I'll argue that the FI has superior atomization, and should make a little more power at every increment.
