331 2X4 setup with extra carb. I Fat fingered it's a 2X4 set up sorry for the confusion This has a progressive linkage set up so it wont be a total gas hog unless you make it so both carbs open at the same time but you know that. Intake is cast iron look at the casting numbers and investigate if you want to know what it came off of. Casting number on the intake is 1464580 I had it on my 1955 331 Caddy motor. Shiping will be actual or just pick it up I can send pictures if requested I haven't figured out how to attach
