Selling a 1957 Holley series 4150 4 barrel Carb ECZ V List 1273. This was the Ford/Merc 312 4 barrel carb. This carb is in good original shape but should plan on it needing a full rebuild as it’s been sitting for a long time. It came with a 312 I purchased but I’m using a different setup. Missing plastic choke cover otherwise appears very complete.
