Carburetor, Holley, Street Avenger, 770 CFM, Electric Choke, Vac. Secondaries

770 CFM Street Avenger Carburetor, Electric Choke, Vacuum Secondaries by Holley®

Street calibration and quick-change vacuum secondaries balance response with easy adjustment.

This 770 CFM Holley® Street Avenger four-barrel carburetor uses street-focused calibration for low-end torque, acceleration and top-end power. The factory-set electric choke assists cold starts, while the quick-change vacuum-secondary housing makes spring changes easier when tuning response or economy. Clear fuel-level sight plugs support float adjustment. Four vacuum ports provide timed, full-manifold and PCV connections. A bright polished finish complements the engine bay. Built-in fuel filters and a fuel-line kit are included, and each carburetor is wet-flow tested. The square-bore mounting flange requires a suitable adapter on a spread-bore intake; automatic-transmission linkage may require additional hardware.
