EDELBROCK SUPER VICTOR #1
To finish off the testing on carbureted intakes for the LS3, we ran an Edelbrock Super Victor equipped with a 4500 (Dominator) flange with two different carburetors. For this test, we installed the same Holley 950 Ultra XP carburetor used on all the previous intakes, as it also featured the Dominator bolt pattern. The idea was to find out if the intake responded to the increased airflow offered by the larger throttle opening. Equipped with the Holley 950 Ultra XP carburetor, the Super Victor produced 556 hp at 6,900 rpm and 557 lb-ft of torque at 5,300 rpm. Despite the big-boy carb flange, torque production down at 4,000 rpm was a respectable 489 lb-ft.
