Description
If you’re building a high-displacement naturally aspirated engine in the 406–430 cubic inch range, this 4-barrel carburetor delivers the air-fuel metering precision you need for consistent power and throttle response. The 850 CFM capacity is engineered to support aggressive power curves without starving your engine at peak RPM, while the mechanical secondary design gives you predictable fuel delivery as boost climbs.
