I have a used 650cfm Holley 4777 drag race carb. Was told that it was in very good shape and was re-worked to run on the 455 that I got it on. Was on a built 455 engine that threw a rod. I bought the engine and here the carb sits. $125/bo + shipping from NH 03110 Pics at: http://picasaweb.google.com/tom.wolf...D88YWC5fSA1wE# Tom
