If Stock it is a 600 CFM Holley 4180. The 4180 was a smog carb that was built by Holley for Motorcraft. The tag on it is very important if you ever have to rebuild it. It contains a Motorcraft # NOT HOLLEY#.
I am trying to figure out what type of carb I have on my
1986 Ford Bronco. 351 winsor with elec. choke. all stock original owner. Local ford dealer no help.
The list number I found is list 50264-1
and just below that number is 1606
I need to get a rebuilt kit, but not sure of the Holley Number.
Is this a 4180? If so will the 3-1346 holley kit work?
Since this is an 86 Bronco, I guess the carb was built in 85.
I am going to get the Holley rebuild kit and give it a try.
The carb has not been much trouble over the years, except it will not pass a gas station, about 10mpg around town.
