ok the Carb on my 65 F100 has 1-14 on the side, is 2 barrel. Is it got the venturi's? Is so, how is this different than other carbs?

Tag on carb says C5TFY

 

All carbs gots venturis, elsewise they'd be worthless as a t'mater can.

Seriously, a venturi is a restriction that causes an increase in air velocity. That increase in air velocity causes a pressure reduction that sucks fuel into the air stream atomizing it. That's what every carb does.

Is your question whether the carb you have is the right one?

 

No didnt know they all had them, as this is my first project of a automotive type I seem to be learning by leaps and bounds lol!

ok, How does my carb differ from what is a dual venturi carb that was on the 351 windsor cop cars, I am sure that they were on other vehicles, but that is what I remember the dealer talking to me about when my patrol vehicle was messing up.

Thanks!

 

C5TF-Y = C5TZ9510M .. 2V Carburetor = 1965 F100/350 352 w/a manual transmission.

The same basic Auto-Lite/Motorcraft 2V was used 1962/74 on all FoMoCo vehicles.

The 2V carb kit is the same for all of them.

After 1974, there were myriad different 2V's until EFI was introduced in the 1980's.

 

Carbs are described as 2v or 4v as an example indicating 2 venturi (barrel) or 4 venturi. Venturi = barrel, or passage directly through the carb body where the air and fuel mix. Remove the air cleaner, look down, and however many large passages with throttle plates at the bottom you see, that's your venturi number.

Ford did make a horrible "variable venturi" carb in, what?, the 1980s that you may be thinking of. Most of these have been sent to the trash bin and replaced with standard carbs by now.

 

Variable was what I was trying to recall, thank you for that! What made the variable such a pain?

 

Does the 1 14 on the side have to do with the jets? What do those numbers mean? This is the 2100 right, carb? What cfm is foing?

 

The VV was the most miserable carburetor foisted on mankind.

While most have been replaced, in CA that isn't the case.

CA smog tests all vehicles 1976 and newer, so the turds have to remain on the vehicles.

65F100390: 1 14 does not refer to jets. What it does refer to, I haven't a clue.

Three different jets were offered for the C5TF-Y carburetor.

2) C3UZ9533A .. Carburetor Jet / #52F = 0-5,000 ft. (Motorcraft CJ133).

2) C3UZ9533C .. Carburetor Jet / #50F = 5,000-10,000 ft. (Motorcraft CJ141).

2) C3UZ9533D .. Carburetor Jet / #48F = 10,000-15,000 ft. (Motorcraft CJ142).

 

The 1.14 is the venturi size and can be looked up to see how many CFM the carb can flow.

This site will show a lot about all the major parts of a Ford engine and drivetrain.

The simple answer is they simply didn't work. Sometimes a bad design is just that. I can't tell you specifically why they were so awful, I just know that I had a lot of repair shops installing Holleys in place of those when I worked behind the counter in the mid 1980s.

 

Sweet, thanks guys, made my monday with all the info and the link to carbs. So much to this site I forget to look sometimes!

I have thought of going to 4v, anty thoughts or ideas?

 

Just don't use one of those cheesy adapters to mount it on your 2-brl manifold....
