so im fed up with trying to trick the smog guys with me non-egr 4 barrel intake maifold. where can i get a cheap EGR manifold? i'm going to the junkyard tomorrow homefully to find a cast iron 4 barrel 302 maifold with EGR. good idea?

 

The EGR on a lot of the Fords is just a spacer plate under the carb. I would look for a truck that had a 351w HO or a 460, and see if you can find the 4bbl spacer plate that has the egr mount on it. Then see if it will fit on top of the manifold you have now.

 

I have one of those EGR plates (with the EGR still on it) sitting in my garage right now... I've been using it as a door stop.

I'll look at it tomorrow and see if it's even useable... If it is, I'll let you have it for a few bucks + shipping if you want it.

 

no no no, thats not what i'm asking. sorry i didnt make it clearer. i want a 4 barrel intake manifold that has EGR drilled in it. my current intake has no EGR slot. EGR spacer i'll get from summit, edelbrock sells a nice shiny one (i like shiny things, lol), so i guess what im asking is, what years could you order a 302 with a 4 bbl intake?

 

Up to 1984, I think they came factory with carburetors. After 1985, the 302's were switched over to EFI.

 

Ford never made a truck 302 with a 4bbl that I know of. They where all 2bbls. The only 4bbl egr 302 manifold you might be able to find would be a 83ish to 85 mustang manifold.

So if you want to get technical about it, to be perfectly legal you need to go back to a 2bbl carb and manifold.

 

O.K. Now I'm lost. I understand what Franklin2 and Wild Karrde are talking about. I plan on sticking one atop my Edelbrock Performer RPM, and am even considering modifying it as a sleeper nitrous plate. I wonder if Kuskoal really knows what these things are, because, I don't see the problem. These are not an EGR spacer plate, they are a combination carburator spacer plate and EGR. Why not spend all that extra bling-bling money at Summit on an EGR equipped Edelbrock manifold? Am I missing something here?

 

Doug,

The EGR itself is attached to a plate under the carb.
The Manifold must have a slot that goes through to the exhaust crossover in order to use the plate.

Edelbrock makes 2 styles of manifold, one that includes this crossover slot for use in emissions controlled vehicles, and one that does not.
The manifold itself is not "equipped with" any EGR valve, it merely accommodates it.

 

I understand. I guess he has to worry about someone actually testing the EGR. I plan on modifying whatever is necessary to make it "look" legal for an eyeball emissions check. I never meant to imply that the Edelbrock manifold came with an EGR, but I am still a little confused about the difference in the Edelbrock manifolds. I was under the impression that the EGR "equipped" ( how about "ready?"), manifold mirrored the small block 2-barrel EGR manifold in that all you had to do was bolt up the EGR valve. IDK. But why, if a slot is the only difference, can you buy an adapter, (curiously similar to the EGR plates previously mentioned), to convert a non- EGR Edelbrock to an EGR ready manifold?

 

The slot is the exhaust supply to the EGR. Unless you have a external pipe that supplies the exhaust like on the EFI engines, a none EGR manifold cannot be converted to EGR.

In my first post, I was hinting to the same thing your were saying, just put the plate on there for looks. If they are getting that picky, then technically they should not pass the 4bbl carb being on there at all. What a mess.

 

You can always take the EGR gasket as a pattern and make a "blank-off" plate to close off the EGR ports and then bolt everything up as before. It will look right.

IDK about the 2 barrel manifolds but there is a distinct difference in the 4 barrel carb mounting boss on my new 460 EGR Performer v/s the non EGR manifold I saw in the speed shop.
I still needed my old EGR spacer to make it work.
Never heard of an adapter, is that for the EFI manifold, or the 4 Bbl? The ports are different.

 

This was actually for a 351w, and it was quite a while back while I was shopping price and decieding which manifold to use . It was more expensive to buy it and the manifold than an EGR manifold and it got me to wondering if I wasn't mistaken about its application, so I grabbed an old Summit catalog and went looking. I couldn't find it, but I've had that happen before with stuff I knew was there and found it later. Being a while back, I don't know if it was in the Summit catalog or the aftermarket book at O'Reilly's. I'll have to find it and let you know. The looking around that I've done showed me that the EGR manifolds use the same plate that I was thinking of, so maybe that's what I was looking at and was mistaken as to which manifold it was for and it was just being offered for sale independently. It was for a Performer 4-barrel intake, as that was all I was looking for at the time. BTW, I plan on grinding the "Performer RPM 351W" off my intake, and I'm thinking about making a mold of stock Ford intake casting markings and applying them to the Edelbrock with PC-7 and painting it old Ford blue. Coupled with some plain tall valve covers painted to match, (to make the intake appear shorter), and hiding the carb under the stock air cleaner, should make it look pretty stock at first glance.

 

i think i have an answer to my egr problem: http://www.flemworld.com/Hto/351w.html it you scroll down you can see a how-to to make an egr work on a non-egr manifold(must drill and tap manifold) and i think all 4bbl egr plates are pretty much the same

 

I wonder if you could fill the cavity in with JB weld. Looks like he got the machine shop to weld it shut. I don't know what he means by "drilling and tapping a 1/2" hole"? If you are going to run tubing, I would drill and tap for a 1/8" pipe thread, so you can use brass compression fittings and copper tubing or steel universal fuel line.

Will the edelbrock egr manifold let the factory egr plate fit? If so, it may be less work to sell your manifold and buy the egr type. Or I guess the edelbrock manifold may have it's own egr plate for more money.

 

Serious temps here....On my 460 manifold Edelbrock includes a chromated steel, 1/8" or so, plate (to protect the Manifold from erosion I assume) This goes under the 'stock' EGR spacer in my application.
I assume welding up the spacer's "slot" and drilling a single hole has the same effect.

**once again, this is MY application, but I assume others would be similar**
