Ford 7200 vv carb.
 
I have heard these are a "finicky" carb, is this true? Who does work these into race carbs? How hard are they to work on compaired to any other carbs?

If you insist on running one, keep a couple of spare diaphragms in your tool box. I can not imagine anybody wanting to run one.

I worked on those things. In the eighties. I do not miss them. You might bolt it on an engine, but you will not make it into a race carburetor.

The reason I asked is the combo I have been looking at comes with this carb. As per NHRA stock rules, you are allowed to run the latest non-computer carb; this carb is computer controlled. What I have been looking for is the specs to this carb so I can find a compatible carb replacement. I have been looking online but I haven't found anything yet.

I suggest you contact Glendora, or at least your division's tech staff.

If you look, the blueprint guide may have the throttle bore diameter listed, and you may be able to find some sort of Ford OE carburetor that has the same throttle bore diameter, that they will allow as a replacement. The previous models probably used some version of the Motorcraft two barrel, there may be one of those that can be used in place of that perverted abomination they called the 7200 VV.

Re: Ford 7200 vv carb.
 
For some reason, when I download the engine spec sheets, I get alot of mumbo gumbo with it and have to decipher everything to get the right specs. As far as non elect. carb goes, 2700 carb is the non elect. of the 7200 from what I have gathered. Obvious choice would be 2150 carb, but until I email Glendora, I won't know.
Now, if I get a no from Glendora, how would I go about getting the 2700/7200 carb to work? Is removing the varible venturi legal modification? What makes this carb so "evil"?

If they won't allow a different carb, you would be wise to change combos. It is a trouble prone P.O.S. as we have tried to make clear.

In a word, JUNK!

Guys, we're not building a daily driver here.

Seems to me, it only has to be part way open on the line and then WFO the rest of the way!

If it were me , I'd figure out how much air it would pass, and then decide if I wanted to make it work.

They won't flow much. Very small. Cars that came with them were very slow. A plain old Motorcraft 2 bl, or the small Holley replacement really woke those cars up. It had better have an extremely low hp factor. If you are at all familier with that mess, you know it was an emissions/gas mileage deal that just did not work out. Those abortions were thrown away right and left.
Guess Ford thought it was time for another Edsel. LOL

Was just thinking about that 350 Olds / Caddy Seville I changed over to a Qjet.
The FI system was junk!

That was before I started tuning EFI. Never tried to hack those ECUs. Did, however, have a fix for the extreme lean idle & tip-in issues they developed. A 36" drill bit in a pin vice. The plastic tube to the MAP sensor got a hole drilled in it. They has a rubber hose slipped over one end. Played with that with my 4 gas infrared exhaust analyzer hooked up. Very high HCs, eratic idle and tip-in stumble was common after 50,000 or so miles. First car, I drilled too large a hole, was right next to the runner tube. Just slipped it forther onto the plastic tube to cover the hole. Knew I was onto something just went too rich. Found .036" was good for about all of them. Ran like a different car.
Had other shops ending them to me for 'the fix". LOL

Yep. Still slower than a Q Jet.

I never heard of anybody that had any success making a race carb out of a 7200 v v.
Last one of those things that I worked on I wouldn't even charge the customer, only thing I wanted was a promise not to bring it back.

That's what I asked of them if they wouldn't let me replace it. LOL

After alot of research online, asking the right person via private message on here, the combo is doable WITH the 2700/7200 carb, was even told it would be a step backwards with a 2150. Am I set on this combo, not quite yet but real close to it.

Then you asked the right person...I'll bet I know him.

And I bet I know where my converter will be coming from when that time comes.

If you are set on using that abortion, I would look into locking the slides all the way open. I never saw one hold them fully open on my chassis dyno. I also never saw one fail to pickup 10/15 hp at the tires with a plain old Ford Motorcraft 2bl. The difference driving the car was noticeable over a good working VV.

Hope it has a very soft hp factor.
Best of luck.
