In 1050 or 1150 cfm, these 4-barrel race carburetors build on the Dominator® design to produce top end horsepower and torque in high-end engines. Three circuit metering adds a level of transition, requiring less pump shot. The metering blocks have changeable emulsion jets, idle feed restrictors, and power valve restrictors to endlessly tune almost any engine.
