When car guys think of carburetors, they instantly think of Holley. Holley's model 4160 four barrel carburetors provide maximum performance on street and mild race vehicles. Most of these carbs feature vacuum secondaries with a metering plate that has no jets, power valves, or accelerator pumps. That makes them easier to tune than full race carburetors with temperamental secondary metering blocks and dual pumps. Plus, they're available in your choice of universal or direct fit OE replacement versions with all emission provisions.
