I have dyno tested those two intakes and a Torker 2 on CA pump swill years ago with the same Holley List 80496 950 HP with no changes to the carb or tune up.
The RPM was better on HP and torque below 5500 RPM at WOT: up: The Torker 2 was the worst: down:
Most of the single plane intakes I've owned and driven on the street are pretty lazy to light throttle response below 2500 RPM
The dual planes are way better below 2500 RPM at light part throttle driving on the street
