Rovernut, your PM box is full.

Now that I dug it out, is this even the stock carb?

Sorry, never noticed the 30 message limit. I deleted all my sent, but can't delete from my inbox.

I don't know enough to know, other than my shop manual only lists the 4180 for the 460. My guess would be someone installed an aftermarket at some point before you did.
Thanks for checking though. Maybe someone else can use it. There's always ebay.

Yes, that is one of the Carter AFB performance carbs. Maybe Gary Lewis would like it, he is into the Edelbrock (they bought the rights and sell them under their name). Either that or someone else who likes the AFB over the Holley.

Re: Carburetor Question

Great question! I am considering getting a new carb from my 1980 F100. It has a 1bbl carb w/electric choke. The original in the truck is a Motorcraft. Anyway it was rebuilt ~8 years ago by a specialized fuel shop and while it ran better, it never purred. So, I been trolling the web for possible replacement sources and found National Carburetors at New and Rebuilt Carburetors Starting From $99 & Free Shipping!

Hope this helps you, others out

Good night Ford Truck Enthusiasts

I haven't been able to locate anything that identifies the differences between 4180's.
For instance, what is the difference between my E6HE-9510-AC LIST-50305-2
and a E6HE-9510-GA LIST 50252-1 ?
I'm trying to figure out what my options are for used ones.

Go to the Holley website.
Look under their Tech section for numerical listings
Look across the tops of pages 15-16 for various 4180 applications.

-AC and -GA are different ford engineering revisions.
The list # is Holley's way of differentiating them.

Like I said before, almost any carb off a 460 truck will be fine.
5.0 Mustangs and 351 trucks will not likely be properly calibrated for your application.

Well, I'm not having much luck finding a carburetor for a reasonable price to rebuild, so I'm thinking of maybe just installing an Edelbrock, then rebuilding my 4180 and ebaying it.

So I've been reading on them and know I need to install a fuel pressure regulator. It seems the one most people are using it the Holley 12-803, but I'm wondering how those are working out. Supposedly the 1406 carb needs about 5-6 psi, but I'm not sure if I'm reading the specs on that regulator correctly.
Low Pressure 1-4 PSI
High Pressure 4.5-9 PSI
Does that mean the low pressure side to the carb is 1-4 psi, and the inlet handles 4.5-9?
Or does it mean the lowest pressure settings can be 1-4 and the highest can be 4.5-9?

This would be on an '85 F-250 460 with the electric fuel pumps and hot fuel handling.
Any other engine/emission variations that might affect what else I need?

Tom, if yours has the hot fuel handling package, you shouldn't need a regulator, I think the electric pumps are in the 1-3 psi range. You are correct the high side is inlet.
