Hello everybody, could you help me identify this Holley carb please. I know it's hard to tell by just one crappy picture but if you could tell me where to get the numbers off it I would post them. It looks like a 4 barrel, electric choke, vacuum secondary model. Thanks for your help.

 

Right there in the center of the picture where the light is brightest is the bowl vent, to the right side of that facing it this way you should find some numbers.
One should start as List- could be list-1850 and have something after that to like list 1850-2 or something like that. Those numbers will tell you what carb it is supposed to be..

I can almost read them but not quite..

 

LIST 6619
0734

 

model 4160 , 600 CFM , 1970-72 Chevy , GMC RV appl. 307-402 Eng. all trans.

 

Thanks for the help. Crappy though I was hoping for 750. Oh well I'm sure I can find a used one for cheap around here and rebuild it. What's everybody running these days? Holleys or Edelbrock?

 

Not an authority: been running a Holley 1850 (4160) on the 65 F100 for 10 plus years. Couple years back decided to rebuild but first purchased a used 1850 off ebay, cheap, which I rebuilt and used as a temporary replacement. Learned a carburetor should be stored in a dry and sealed environment. If it becomes necessary, I will remove, rebuild the original then, reinstall. Found the 1850 is bout as basic as it gets, if it were not for soaking certain carburetor components it would only take a couple hours. An issue did come across, found there are a couple type fuel cross over tube seals. With the 68 289/302, moderate cam, found the Holley originally had #67 jets and by inspecting the plugs appeared to me engine running little too rich, swapped to #65 and seemed to be running cleaner?? This carburetor is the same as what I am running on the 65 w/ the 390, in either case, with the trans and axle gearing rarely, if ever, do I get into the secondaries. Anyhow, had an urge to chime in??
