Hello,

My name is Jeremy and I am new to this forum. I am rebuilding the 460 engine out of my F350. I noticed that the carb has an EGR built in. I want to get rid of this but I heard that if I do, it may cause an issue with pinging or detonation. I have a non-EGR Edelbrock Performer intake manifold coming. Is there a phenolic plate for the Holley 4180 stock carb? What else would I have to do to be rid of the EGR so that my engine runs correctly without damaging other parts?

Thanks all,

Jeremy

 

Getting rid of the stock carb is one way to get rid of the egr and emissions. You can keep the egr plate and just block the egr off, and then try the stock carb, but if you do run into problems, a aftermarket carb is the way to go.

 

Welcome to FTE Jeremy!

There are 1" thick 4 hole phenolic spacers all over Ebay right now. Phenolic 1" 4 Hole 4bbl Holley Carb Spacer with Studs : eBay Motors (item 220685438903 end time Oct-22-10 21:08:30 PDT)

etc....

in my experience you will need to adjust both the 4180's mixture and your timing curve to keep from pinging.

 

Thanks for the advice. The new carb is a little out of my budget range as Ive had to buy one head and manifold already. Still waiting for the block to come back from being cooked and cleaned and bored. I will try blocking off the egr for now. Will I have to retard or advance the timing? I plan on rebuilding the carb so I will adjust the mix then. Thanks again.

 

I'd just set the timing at the stock setting then see if it pings.

 

Try just bolting a thin piece of aluminum can between the neck of the spacer and the valve itself if a $17 spacer is out of reach.... or just fill the port with silicone.

Otherwise there's nothing to block off.
If you got the non-EGR manifold there is no hot exhaust gas port to worry about.

I fount it too lean in cruise and tip in. There's only so much adjustment available in the idle screws before it wants to load up at lights and such.
The annular boosters in the 4180 are great atomizers.

Look at the Flemworld site under '85 How To's to see more about the internals of the 4180 carb.

Hope this helps...

 

I've decided to rebuild this carb. I was wondering if the rebuild kit from Holley will work or if I have to get one from ford? If I can get one from Holley which do I get? Thanks again.

 

as far as I know, the holley kit for a 4160 will work (maybe not just found that the 4180 gaskets are slightly different...). I did mine by getting a kit from Napa based off of the id tag on the carb, that is the best way to do it. If you want better gaskets, you could get a set of the holley blue ones fairly cheap as well.

I am fixing to rebuild another 4180 I got at the JY the other day for my 400. I was simply going to buy fuel bowls (to get rid of the vents) and a rebuild kit based off of the id tag. I was also thinking of using an aftermarket set of adjustable jets, so I don't have to tear it down to adjust it.

 

The tag on this carb is e5pe-bra but oreilly and auto zone could not find an exact match for this. Napa was closed at the time so incouldnt go there. Any ideas on where I can find a rebuild/renew kit? Possibly online? I did get one from Holley for the 4160 but have not confirmed if this will work. I will keep you posted.

 

Holley part # 3-1346 is the correct Rebuild kit for the 4180

 

A 4160 kit will not work for a 4180. Get the Holley kit mentioned above or if you can
find it, a Motorcraft CT-1443-D kit will work for the 4180.

 

At the point of rebuilding the smog carb you'd be better off even with a cheapy 4160 . You should be able to find them for $40 or less, + $20 for a kit. Better yet a 750 4150 VS or DP, though you'd be more around $100 total into that if you find a decent carb to rebuild. Those small smogger carbs leave a lot of power on the table with a 460 though. A 750 or 850 would be best.

Also since it sounds like you have it apart now, it would be a good time to port those heads.Even if headers aren't in the budget now, porting the heads is basically free if you have a few tools and some time. It'll pay off later, and even with log manifolds will help in power and MPG. The exhaust ports on these heads are terrible and it's just about impossible to make them worse than they are as cast. If you are interested in porting I can give you some pointers and I'm sure others can too.

 

The annular discharge boosters and vacuum secondaries make the 4180 a good carb when set up properly. It's not a carb that someone would go out and buy, but it's worth modifing in my opinion. The "smog" holes can be plugged or you can use different float bowls. Yes, it is okay to plug them because that is not their only source of airflow.

Although I do agree that a 460 would likely benefit from a bigger carb.

 

I have to get the heads back from cook, clean and crack check, but yes I had thought of porting the exhaust. And thanks guys for giving me the part number from Holley. I was able to find it online right away.

 

The 4180 can be desmogged easily. Plug or cap the vent tubes on the float bowls,
changed the two stage power valve to single stage type, and maybe increase the
primary jets by one or two sizes. Run the carb with the stock jets before you try
the larger ones because you may not need them. The annular boosters on the primary
side are what is great about these carbs.
