OK guys I need some info. I am having a hard time finding info about a Holley 4110. Took me long enough to find out what it was even. Holley's catalog doesn't even list it from what I can find. I may need to get in there and change some jets around and I needed to know if they were the standard ones or something special. Also, will the electric choke that fits on all the other Holleys work on this one?

Thanks
Trey

 

Sure it's not a 4010?

 

You're right it's 4010. It's the one with the cast on bowls but the top plate/air horn covers all that up.

 

On the airhorn you should find numbers similar to these to tell you exactly what it is and the supplied jet sizes.
The 4010 and 4011 were both the same style.
They are a copy of the old Ford Autolite 4100 carb from the early 60's and really are one of the best carbs ever made, they just didn't go over well with the perf crowd and Holy discontinued them and support for them.
Other than the top gaskets you can make the other consumable parts fit. Jets are interchangeable.
They are made of aluminum so they polish up nicely.
They also tend to be a little rich at idle and I had to drill out the air bleeds a little.
There is a book, you can find on ebay and also the kits.

Do a search at Summit for parts.
Best thing I can say about them is that they are light

 

Awesome info guys! I do appreciate it. First time I pulled the air cleaner off the carb I sat there scratching my head. This is the only car I have ever seen with this carb on it. The car is running very rich at idle and is not very crisp throttle wise. I'm going to be going through the usual check points to figure this out, but I was really worried about getting the internal parts if I needed them. I couldn't find anything in my Holley catalog.

Currently there is no choke on the carb which doesn't help matters. Plan is to install an electric so the customer doesn't have to deal with a manual. It's his wife's car anyway and she doesn't want to put up with pushing and pulling a ****.

Thanks guys.

 

What's wrong, not a fan? Don't be shy about it if you have some insight on it. I did a google search and some people were praising it but never got into detail on internals.

 

I had a flooding problem with mine, seems they didn't like much fuel pressure above 6lbs, but that may be fixable with replacement needle/seats. I used both the 4010 600 and the 4011 750 spread bore . The 4011 worked the best.
But I when I replaced it with a 600 cfm 4150 it ran like a different car

 

Mine is a spreadbore, mechanical secondary, and it will go back on one of these days.
Put it on years ago when Florida started emmisions testing. Remember that I had to take it apart over 20 times to jet, drill etc to get it originaally set right, but was wll worth it. Ended up passing the yearly emisions with flying colors and kept it on a daily driver for over 10 -15 years with no issues. That design bowl won't leak. Also has annular boosters. Did use only 4psi pressure with it.
With the mechanical secondaries, you could feel with your foot when the secondaries would quick in, but you could also cruise the interstate on the primaries alone at 75mph.
A noticeable improvement over a proper qjet and the fuel economy of a spreadbore.

 

I had one of these. I had a problem with the top cover paper gasket leaking fuel when the car was parked at a severe sideways angle. unfortunately that describes my driveway, so I had to take it off and replace it with the traditional-type holley.

I was kind of disappointed because I had boughten two of these, because the design sounded really good. one square bore, one spread bore.

I wasn't running a fuel pressure regulator, but the fuel pump was the original GM pump for the Quadrajet. Maybe the fuel pressure was marginally too high for this design.

anyways, that's all history now.

 

Memories are returning as to why I had less than positive experiences.....the first time I attempted a jet change and removed the top cover all the screws were cross threaded and brought the threads out with them

 

Well, this one I have here is a 4011-1. Car is just a mild cammed and header 350. No wonder it's running rich.

Is there a source for the top plate gasket?

 

Like I said Summit has a bunch of those carb parts....

I forgot. thanks.
