Also fits Chevrolet / GMC Trucks (1968–1973) and Corvette 327~454 V8 engines (1975–1979). Automotive use only — not recommended for marine applications
- 【Enhanced Fuel Flow & Throttle Response】4MV chevy 350 carburetor equipped with a 750 CFM 4-barrel airflow design (Quadrajet range: 600–800 CFM), delivering smoother acceleration, stronger low-end torque, and improved throttle response. Each unit is precision-machined and flow-balanced for optimal air/fuel mixture — ideal for classic restoration and performance upgrades
- 【Mechanical Divorced Choke】Small Block Carburetor built for the original Rochester Quadrajet 4MV 1901-GG mechanical choke setup. Includes manual choke, vacuum secondary, and spread bore design — ideal for classic or performance engines without computer-controlled chokes, allowing precise control of cold starts and quick warm-ups
- 【Excellent Performance】Every carburetor is bench-tested and pre-calibrated for idle, choke, and fuel flow to ensure consistent fuel delivery and smooth engine operation. This carburetor features an aluminum body, upgraded brass float, and reinforced gaskets to solve common leaks and flooding problems. Minor tuning (mixture, idle, float) may be required depending on engine setup
- 【OEM Fit & Easy Installation】 The quadrajet carburetor comes with complete replacement kit including carburetor, gaskets, air filter ring, vacuum plugs, fuel jets ( extra jets included for custom tuning or specific modifications) for quick Installation. Designed for direct fitment — just confirm mounting holes, fuel inlet, vacuum ports, and throttle linkage before installation
- 【Fuel Pressure Recommendation】Quadrajet carburetors are sensitive to excessive fuel pressure. Maintain a regulated fuel pressure of 5–5.5 psi for best performance. If your fuel pump exceeds 7 psi, it’s recommended to install a fuel pressure regulator to prevent leaks and unstable main nozzle flow
- 【Customer Service】All carburetors are 100% brand new and backed by 12 months of quality support from LOREADA. Please verify compatibility before purchase and refer to online installation videos for guidance (instructions not included). The carburetor arrives pre-set and ready to install, ensuring a smooth start-up experience
