Quite interesting.  Thanks for posting this story.  I have on old college buddy in Casper who is a Chevy fan.  I'll have to contact him and see if he knows of Mr. Alexander.  My buddy used to have a 1968 Z/28, not from the Casper dealership though.  A good friend of his that I met during Thanksgiving vacation in 1971 in Casper had a 1969 Z/28, Burnished Brown.  This car very well could have come from this dealership if it was in existence then and could have been sold by this gentleman.

I've heard wheels were changed from AD to YH as a result of the availability of the 4 wheel disc brake option. When did that option begin? My impression has been around Jan 69, and also that's about the time the wheels changed over. How long would it have taken for a YH wheel with a 17 Dec manufacture date to make it to the assembly line? The assembly plant would also have to be notified so that the broadcast sheet could be revised from AD to YH correct? Any broadcast sheets out there from this time frame?

My Van Nuys 1969 Z with an 01C build date has YH identifying the wheels on the chassis broadcast sheet.

Happy Birthday John.  Like all the others on this site I much appreciate your knowledge and your willingness to share it.  I only wish that you lived closer so I could meet you and use your expertise in person in trying to get my '69 Z to run right.

Loved those ads.  Thanks for the memories.

The biggest difference I have found between original air cleaner decals and reproduction ones is that the original ones had the foil finish applied over a thin manila colored layer of cardboard, like the photo Z28-RS posted of his original one.  A few years ago now I stupidly replaced my original one because it was peeling away on the edges with an all foil one.  I'm waiting for someone to reproduce one with the correct thin piece of cardboard under the foil top.

Happy New Year to all you guys.  Hope the new year brings good health, happiness, and finished car projects.

A Merry Christmas and a Happy New Year to all you guys.  I can't believe all I continue to learn from this site.

Thank you John.  Glad to hear it is something as simple as you described.

I finally got the AIR system inactivated.  Checked for a vacuum leak around the carb and couldn't find any.  Car seems to hold an idle now without slowly going down and dying.  One thing I have noticed since I have been doing a lot of work with the air cleaner off is that after the car has idled awhile, though still not anywhere near hot, after I shut the engine off a vapor or mist almost as thick as smoke comes out of the carb throat.  The carb is still cold to the touch when this occurs.  What is causing this?

It's great that you were able to talk with your car's original owner.  Hopefully he will be able to send you some of his old pics of it.  I was able to talk with the original owner of my '69 Z and get some history on it.  He sent me some photos of it when he had only had it 2 months.  I and a lot of others I'm sure enjoy finding out as much as possible about our car's early life.

Good to hear everything is going so good for you and for your '68 Z.  Can you actually buy 116 octane leaded gas from a pump at Sears Point, or do you have to buy it by bulk in 5 gal. cans?

That's great news Danny.

I wanted to thank all you guys once again for your responses and help.  I am taking things one step at a time.  I think it has been narrowed down to a fuel percolation problem with excessive heat being produced from the exhaust manifolds due to the AIR pump pumping air all the time, due to a broken diaphragm in the diverter valve, plus a vacuum leak from the same cause.  The cooling system checks out fine.  The timing checks out fine.  I'm still looking for a racing gas distributor in my local area. 
What do you guys think about Joe Gibbs Driven Carb Defender Fuel Additive, for counteracting the ethanol in gas, possible help or waste of money?

I plan to have my smog pump deveined and the screws put into the exhaust manifolds in place of the extension tubes.  I have 2 questions:

What is the easiest or best way to completely degut the smog pump?  What do I take out and what do I leave?  I am guessing when done it will just have a rotating pulley on the outside, but what is left on the inside if anything; is there still something rotating on the inside? 

What screws exactly do I need for the exhaust manifolds?  I have read on other posts here on CRG that they should be stainless (I am guessing steel), #10 x 1/2 in., flat top.  Where is the best place to get them, hardware store or auto parts place? 

Thank you.  I really appreciate all the help from all you guys on this website.  I wish I knew more about first gen Camaros, especially mechanical wise.

You don't have a cooling problem, you have a typical fuel percolation problem, aggravated by low E10 fuel boiling points.


Since John brought it up, let's discuss fuel for a second - any local station carry straight (non-ethanol) gas, and/or what are you running through the motor ? I would not recommend any E10 gas for any early engine, especially one that uses neoprene tipped needles in the carb, or rubber fuel lines. Like John indicates, the percolation is a problem, plus the stuff eats everything else, and has an affinity for moisture build up in the tank. Nothing draws a vacuum worse than ethanol in my opinion. Find a race gas distributor and run 100+ octane unleaded, or blend it with non-ethanol regular to stretch it.

I would, regardless, clean the cooling system completely, especially if the motor sits for a decent while without running up to operation temps regularly. Buildups are inevitable internally to the block, heads and radiator - keep them clean and they'll function accordingly.

2 cents -

I live in a small town in the Sierra Foothills in California.  There are no stations around here that I am aware of that sell non-ethanol gas.  I use premium Chevron, Shell, or 76 in it.  I'll do some research to see if I can obtain unleaded racing gas in my local area.  My car does sit every so often, sometimes up to 2 months between my taking it out for a spin.  I plan on having the radiator and engine gone completely over to check for gunk build-up.  Thanks for your info.
