Just bought a 455 GS project. It has a Holley carb on it. Numbers on the side are 12R 10656B. I don't see any other numbers. What is it? Thanks in advance.
John, Get the List number that is stamped into the front side of the raised choke tower on top of the carb that holds the choke butterfly. If you get me the number I should be able to tell you what carb it is. Thanks, Mike
Here I go raising the dead!!!! :laugh: I have the same carb. side: 12R-10656B front:R84015 1809 same question as originally asked. Sorry to bring up 5 year old posts!!
