Okay... So frustrated with my engine I spent a grand and got some parts that are dying to go on the engine. I have the clifford single-plane intake, Edelbrock 500 cfm performer carb, EFI exhaust manifold (rather than headers), K&N filter and a new air cleaner setup... I found a shop to do the exhaust for about $680. Totally ready to dive-in, I called the mechanic to see what he would charge me to do it. He said he can't do it at all if it isn't smog-able. So, here's the question. Anyone know where I can get a smogable carb riser/egr plate for this setup? I am dying to put it on, but I can't make my truck undriveable. So, any help here would be great. If you happen to have an egr plate that the smog pump screws into lying around... I would be happy to take it off your hands.


THANKS!

 

Look here:

It'll tell you how to make your own EGR plate. (Series of 6 articles).

 

Gene, the only problem I see with this is that the clifford intake doesn't have any holes in it. Do I just pick a place and drill it? Also, the smog pump has a 3/4" hose fitting that screws in to the egr plate on the current configuration, on the new one with the clifford intake, where do I run that?

If I am not mistaken, on my current setup which is stock, the only place all of this smog crap goes is on the egr plate between the carb and the intake manifold. The guys at National performance center told me that simply putting an egr compatible riser plate in between the carb and the clifford intake would not work because there was no "hole" in the intake for the egr to work properly. Now, correct me if I am wrong here, but I don't recall there being a hole on the stock intake. The only holes came from the egr plate itself. Do cars equipped with 4bbl carbs not use an egr? Can I not use some type of egr setup from a 4bbl equipped car?

This is such a pain. Maybe I will just swap the engine out entirely.

 

This is why I got as far with Clifford as "No, our Ford stuff isn't CARB approved."

Thanks, but no thanks. Not sure what Nv wants, but what CA wants, Clifford ain't got.

Good luck.

 

Calm down man, you'll be OK...

The "input" from the exhaust will come from the rear EFI exhaust manifold. There is a threaded boss there (about 3/4" or 1" if I remember right) that you can use to rig up a series of pipe fittings. No drilling necessary, just a trip to the hardware store to get the appropriate stuff.
From this fitting, you will get the exhaust input which goes to the EGR valve. I used copper piping, but I'm sure there are other ways to do it. On the "output" side of the EGR valve, on the OFFY intake manifold there is a boss on the passenger's side of the manifold that the EGR gasses can pass through after being attached with the appropriate fittings. You can probably have the same thing milled into your manifold or use a carb plate.

Here is a pic to show you how I (emphasis on the "I") did it, but I am sure there are other ways too.:



Below the carb, in Blue "JetHot" coating, you will see an O2 plug sticking out of the EFI manifold. Directly to the left (also blue) you can see the device I used to extract the EGR gasses from, utilizing the pipe fittings stated earlier. What you DON"T see in the pic is the copper tubing jutting out of the top of that device, going up, and around the other side of the carb. In the pic, the copper tubing emerges from behind the carb (by the fuel filter) and goes into the EGR valve-plate itself.



In this pic, you can see the copper "return" line from the EGR plate come out of the plate, cross over the top of the intake manifold, then drop down and enter the intake. You can see this right below the carb, inside where the braided hose loops around.

Like I said, I'm sure there are a ton of ways to accomplish the same thing, but you have to fabricate the EGR plate before you can do anything.

Good luck

thats a clean motor, i like. 680 for exhaust is a little much. I think you should have a friend tow it in, and tell the guy its for drag racing, bracket racing to be specific if you still wanna blow 700 on exhaust, i paid 300 for mine, cat back, flowmaster 40 single in dual out, 2 2 foot 3.5 Inch tips with 3 inch DIA all the way from the cats back...

That is great looking engine, I'm jealous, you do nice work!
How much do you have invested in the engine if you dont mind me asking?

 

$680 for the exhaust?


What exactly are you having done, as far as the exhaust?



Would you have any interest doing the work yourself? Its just a few bolts...surely, the folks on here could get you through it. Good luck
