This is an NOS Holley #6497 spread bore, replacement, carburetor for 1970-1972 Oldsmobile 350 & 455 engines. It is a 650 cfm double pumper. It has the same stock emissions calibrations for the years specified. Connects directly to the stock choke and throttle linkage. It includes a new throttle cable bracket, base gasket, studs, fuel hose, and instructions. ONLY the fuel line must be modified to fit the side facing inlet. The carb was manufactured 1n 1984, and has been in my possession since 1994. It has never been mounted or had gasoline in it.
There is nothing like a new carburetor. These carbs run great and work well on later years also. They do not fit earlier years because the chokes were different. The carb is specifically listed for 1970-1972 Oldsmobile, it is not a universal application. The calibration is for street and emissions. Asking $300 plus shipping.
