thanks guys.  john do you have any more pic's of that motor. I want mine to be as close to that as I can.   can the EGR parts still be found?
and did the 77 have the choke heat shield? I have one.

[John Witzke]

The choke heat shield was not used in the 1977 engines.  All the hose and wire routings on my engine are factory.  Nothing has been changed.  What you see is 100% factory correct.  I hope these pictures help

Here is another.

Approx 85% to 90% of the engine paint is original factory applied.  I carefully color matched the original paint and touched up a few areas.  Otherwise my engine compartment has all the original factory applied finishes and could be used by restoration people as a blueprint to what the factory actually done.

I hope these help with your project

I think he is the only one that offers this piece currently.

As for the parts avaliability of the EGR parts.... I would have to say that your local GM dealer or parts store "should" carry them

thanks Virgil . I do have the heat shield. but john said its not correct for my 77 W72

[Rarebird]

my bad.. forgot what year you were working on...

[4SPEED]

I did some Google searching. all I can find is the egr valve, none of the other parts. any of you guys have the parts? and willing to sell them? 

[ta78w72]

Virgil, what is that beside the EGR ? the silver thing with the vac line going to the front of the intake.
will I need one on my 77 or are all years different?  

That's the back pressure transducer.  The new egr valve incorporate that into the valve itself.  I believe that assembly is still available at Clean Air Products 1 800-help.  They have a lot of these kinds of things for Pontiacs.  If I recall correctly, it's about $200.  But that would replace the EGR that you have with the original type part that has the back pressure transducer hanging off the egr valve.

But you should call him and send him a picture of that particular part to make sure you get the right one.

Thank you again everyone for the pictures.  I got everything hooked up except for the three brackets for the Air conditioner condensor.  I could never see John's pictures until I realized I had to log on.  Doh..  Now that I have seen his pics, I should be able to put the three brackets on.  Will try and get pictures as soon as I can.  Stopping for the day... I'm beat.
