4-Barrel Carburetor and 650 CFM Square Flange Carburetor assembly. Featuring an annular booster design for consistent fuel atomization across the RPM range. The physical square-flange base supports a 5.160″ × 5.625″ bolt pattern, compatible with standard aftermarket high-performance intake manifolds.
Constructed with a lightweight satin die-cast aluminum body for thermal stability under engine bay heat cycles. Includes PTFE-bushed throttle shafts and machined throttle plates to maintain mechanical movement precision. The manual choke mechanism provides direct mechanical control for cold-start fuel enrichment.
Addresses fuel delivery fluctuations in older square-bore carburetors. This 4-Barrel Carburetor restores factory-standard fuel-air mixture delivery for naturally aspirated V8 engines. The internal metering rods and primary/secondary jets are pre-calibrated for out-of-box mechanical integration with street-performance setups.
Package includes 1x 650 CFM Carburetor, 1x Base Gasket, 1x Fuel Inlet Fitting, and mounting hardware. Installation Limit: Not legal for sale or use in California on pollution-controlled motor vehicles. Professional installation is mandatory; verify fuel pressure (max 6.5 PSI) and linkage adapter requirements before final tuning.
