I have a rebuilt Holly 4412 S 500 cfm 2bbl manual choke ford kick down and linkage it was installed on my 69 ford F 250 390 this is a circle tracker or drag racer type carb Great for a Boat !!!! it is described as a racing carb On Holly website I rebuilt it with the Holly kit although the 50cc accelerator pump screws need to be replaced there on the Holly site pretty cheap 12 bucks but if your into Holly I'm sure you already have them anyway
500 cfm right off idle to cruise daily driver is not a Good setup the pervious owner installed this and I did not know what I had till I bought the rebuild kit for it there also was a alum spacer underneath to raise the carb Good luck finding that around today for a 2bbl
175.00 for both or 150.00 just the Carb Thanks ......
