Rochester quadrajet 4bl carburetor for a late 60's Big Block Chevy motor. I had this one built for my 1968 427 Corvette. I decided to pull it off in favor of an electric choke version. It was only on the car for a month. I had the unit professional refurbished including replating. It is essentially new. This model quadrajet, #7029200 was used on 396 and 427 engines around 1969. It is a very valuable carburetor, especially in this condition. Asking $680 obo. I have included the divorced choke assembly from my car as well. Please leave a message if you call. Thanks!
