Carb Identification

[fp_5]

I recently bought a '77F250 2wd truck. The truck was originally a 351M but at some point a rebuilt 460 was put in by a Ford dealer(I think). I need to rebuild the Carb and would like to do it myself with the proper kit. Unfortunately there is no tag on the carb and no stamping that i can find on it other than "Motorcraft". How do I figure out which carb this is. I would upload pictures but I haven't been able to do so for weeks now( have asked moderator to investigate). Is there an online reference with diagrams that I can use as I believe that there were several different carbs that are similar but not identical. any help would be great! Thnx, Frank

If its the stock carb than its prob the 2 barrel motorcraft 2100 or 2150.

I'd double check to see if they didnt stick the carb id tag into the glove box or something of that sort. If not id run by a mechanic and have him look at it and im sure he could help you out.

I hope you figure it out, good luck!

Forgot to mention that it's a four barrel(spread bore)...........
I'll look through the stuff I got with the truck one more time, maybe I'll get lucky and find a tag.

Check out your thread in the 73-79 forum.

Motorcraft 4300 or 4350 is what you most likely have. Every one of those carburetors I ever had was difficult to deal with and I ended up going aftermarket.

thanks 460swmo,
Thats the one! The newer spread bore, the lower photo.
Seems odd that they"re both 4300's?? Seems like there's a lot of info on that site, I'll poke around and see what I can find out. If I can find an application guide hopefully only one kit will work a Ford truck of the era.
wishful thinking maybe?

thanks again
