It features two-step metering rods to smooth transitions between fuel circuits, a bottom-feed primary venturi booster for stronger throttle response, and non-adjustable electric secondary air valves for reliable operation. Constructed with durable materials and supplied fully assembled, it arrives ready for installation on compatible intake manifolds.\u003c\/p\u003e\n\n\u003ch3\u003eWhat vehicles and manifolds will this 1406 carburetor fit?\u003c\/h3\u003e\n\u003cp\u003eThe Condgreemee 1406 is designed for square-bore applications using Performer-style intakes.
