Condgreemee 1406 Carburetor for Performer 600 CFM 4-Barrel – AFB-Style with Electric Choke

Enhanced Mechanical Fuel System for Classic GM Powerplants

The Condgreemee 1406 Carburetor is designed as a direct replacement for Performer 600 CFM 4-barrel square-bore setups. It blends traditional AFB-style air valve secondary architecture with modern, durable construction. Two-step metering rods support smoother transitions between circuits, helping to reduce backfiring tendencies and maintain consistent power delivery. A bottom-feed primary venturi booster promotes smoother acceleration and improved drivability across midrange RPMs. Each unit is 100% brand new and built with high-grade materials to emphasize long-lasting performance and reliable idle quality.
