JET Model 4160 Stage 3 carburetors are based on the popular Model 4160 Holley 4-barrel carburetors. They begin life with the disassembly and inspection of the main body for proper sizing of the idle, transition, acceleration, and main metering circuits. The body and metering blocks are checked for straightness, their boosters are aligned in the venturi, and their throttle bores are aligned for proper seating. Next, the fuel metering circuits are inspected, blueprinted, and then calibrated to match the modifications done to the engine. The JET Model 4160 Stage 3 carburetors' air horn is milled to improve and equalize airflow between the primaries and secondaries, and a quick-change cover kit allows for changes in the secondary opening rate in mere seconds. Maximize your performance potential with one of these JET Model 4160 Stage 3 carburetors.

Additional features include:
• Radiused air inlet and modified venturis for greatly increased airflow
• Modified discharge boosters for increased signal strength and atomization
• Machined throttle shafts
• Four corner idle circuits (3310 series only)
• Fully modified metering blocks
• Modified floats
• High-flow needle and seats
