Street engines demand a carburetor that balances airflow, fuel control, and everyday reliability, and this BR-67270 Street Carburetor Assembly delivers exactly that. Designed as a direct replacement for OE part number BR-67270, it combines a 600 CFM capacity with vacuum secondary technology to provide stable fuel delivery across different driving conditions. Its calibration supports smooth idling, reliable mid-range performance, and steady throttle response, making it well-suited for daily street use or weekend driving.
The carburetor is constructed from die-cast aluminum, offering a strong yet lightweight structure. Aluminum ensures resistance to heat, corrosion, and long-term wear, extending service life even under continuous use. Its precision machining guarantees stable airflow and accurate fuel atomization, preventing issues such as flooding, hesitation, or misfiring. By maintaining the correct air-fuel balance, it helps protect the engine from damage and improves riding comfort.
With its vacuum secondary system, this carburetor provides flexibility for different RPM ranges. At lower throttle inputs, it maintains fuel efficiency and steady idle, while under heavy load or acceleration, the secondaries open smoothly to deliver additional airflow. This balance enhances drivability, offering strong response when needed without sacrificing everyday efficiency.
Installation is designed to be straightforward. With a single fuel inlet, 4-barrel configuration, and OE-style specifications, the carburetor mounts easily onto compatible intake manifolds. Its setup reduces the need for complex adjustments, making it suitable for both professional mechanics and skilled users who prefer to handle maintenance independently.
Performance is further supported by calibrated components, including primary jets, secondary jets, and power valves. With primary main jet size 70, secondary main jet size 74, and a 6.5 in/Hg power valve, the carburetor ensures consistent fuel delivery tailored for street conditions. Outer and inner air bleed sizes of 70 and 28 further refine airflow regulation, supporting precise combustion and reliable power output.
Applications include a wide range of street performance engines where a 600 CFM 4-barrel vacuum secondary carburetor is specified. This configuration offers versatility for enthusiasts upgrading or restoring vehicles, providing dependable operation across a variety of conditions. Its OE reference ensures compatibility for those seeking a replacement without sacrificing performance quality.
Every carburetor undergoes quality testing to ensure it meets or exceeds original specifications. With stable combustion, reliable throttle response, and durable construction, this BR-67270 carburetor provides the balance of efficiency and performance that street vehicles require.
