These manifolds utilize modern induction design techniques for incredible race-winning power. The all-new Super Victors deliver maximum torque and horsepower up to 8000+ rpm. The extended, constant cross sectional area of the runners produce more torque across the mid-range for great short track power, throttle response out of the corners and improved 60-foot times in drag racing. A direct ''line of sight'' flow path provides max flow for outstanding performance. Super Victor #E11-2925 is designed for heads with a standard port location and the runners match the ''flat floor'' entry of the latest 23 heads. Carb pad height is 5-1/2'' (from end seals) and overall, the #E11-2925 is about one-inch taller than our Victor Jr. intake #E11-2975.
