Proform 750 cfm vacuum secondary carb, 4150 Series. It’s new came with a 462ci Buick motor that I ended up selling, tried it on another stock 455 Buick, but ended changing that out for an Edelbrock carb... Summit lists this for like $500... $320 Shipped to lower 48.. Need to sell it to get cash for race car upgrades.... Thanks Gary G
