Vintage Holley 1850‑3 4‑barrel carburetor, stamped LIST‑1850‑3 with date code 0189 (January 1989). This is one of Holley’s most popular street‑performance models — a 600 CFM vacuum‑secondary carburetor designed for broad compatibility across Chevrolet, Ford, and Mopar V8 engines.

This model features a single fuel inlet, electric choke housing, and the standard Holley 4150‑style flange pattern, making it a direct fit for most square‑bore intake manifolds. It’s an excellent candidate for restoration, tuning, or use as a complete donor core for a rebuild
