Performance Carburetor 870CFM Aluminum Avenger

The Performance Carburetor 870CFM Aluminum Avenger by Holley is designed for street and strip engines that require dependable fuel delivery and responsive throttle control. This carburetor is ideal for enthusiasts looking to upgrade mid-range displacement engines or enhance fuel capacity in moderately boosted applications, ensuring stable air-fuel ratios across varying load conditions.

Constructed from lightweight aluminum, the Avenger carburetor not only reduces underhood weight but also maintains structural integrity, which is crucial for consistent fuel metering and resistance to vibration. The 870 CFM rating provides a balance of mid-range responsiveness and sufficient airflow for engines in the 350–450 cubic inch range, preventing overly lean conditions that can occur with oversized carburetors. Holley's vacuum secondaries and accelerator pump system facilitate smooth transitions from idle to wide-open throttle.

This carburetor is compatible with most conventional intake manifolds featuring standard 4-barrel bolt patterns, making it an excellent choice for retrofitting classic Chevrolet, Ford, and Mopar vehicles. The aluminum construction also aids in heat dissipation, extending component life and ensuring precise fuel atomization during extended driving sessions. With a fuel pressure range of 4.5–6 PSI, the Avenger carburetor is tailored for optimal performance in a variety of applications.
