The sheets above the gas tank have been found only on Los Angeles built cars.  This car was built in Norwood Ohio.

Do you have the casting dates on the block and the heads?  Reason I ask is,  my 07C car has a VIN number 275 after this car and has an engine build date of 06-19.  Your car has an engine build date of 07-10.  Curious to see if the casting dates match up with the build date.

Hey Jon, thanx very much for that info. It's a lot to take in, especially for a backyard mechanic such as myself. Seen that rubber piece you were talking about, pretty cool. I never knew it was there until I heard it mentioned in one of the replies.

Going to adjust the Valves Sunday. Then pull the Distributor and send off for rebuild. Wish I could also send the Alternator, Master Cylinder, Calipers and a few other goodies.... But that takes $$$     Then will change the oil and the spark plugs again. When Dist. comes back I can drop it back in and start my trouble shooting issue back up.

 In the mean time, found this tag on the car. It was stuck on and seems original. Can you guess where on the car it was located???... Danny

Hi Jimmy.....here is a shot from the AIM.

     

You didn't say what you thought but it looks centered to me.....looks great.

Jimmy...it seems that your photo was taken to the right of the center of the stripe and also at an angle to the stripe thus kinda distorting the position of the emblem in relation to the stripe.  Why don't you just center yourself in front of the stripe and look straight down the center of the stripe and see if the relationship looks better aligned.  Just a thought here.....sometimes camera angles can play tricks on you.

Interesting pulley!   Everyone says that the Z28 should have a deep groove pulley (#3925522) on the smog pump and most of them do.  My 06-19 engine did not have the deep groove pulley....it had the standard groove pulley (#3927116) just like your showing on your engine.  I have never been able to find out exactly why that happened.  Kurt, the site coordinator,  said that he has seen this happen before but he didn't know why either.  So, to be correct, I finally found an original #3925522 pulley and purchased it.  If you are interested, there is one currently listed on eBay for a fairly decent price.   Here is the link.....http://www.ebay.com/itm/VINTAGE-1968-72-BIG-BLOCK-CHEVY-bbc-CORVETTE-427-454-SMOG-PUMP-PULLEY-3925522-/271538620175?pt=Vintage_Car_Truck_Parts_Accessories&hash=item3f38f6870f&vxp=mtr

BTW....my original heads also have that single digit number on the ends.  Own mine, it is stamped so light that it is hard to make out....so I can't tell exactly what it is.

Here is a link to a couple of photos of the '69 routing.....is the same for the '68.  The first photo shows the original routing and the second photo shows the distributor connected to the plastic tee port that the smog diverter valve was connected to.

Very late......My 07C Z28 has an engine build date of 06-19.

What's missing is the Black Plastic insert that fits inside the center hole....it ID's the valve pressure setting.  BTW....mine is missing also.....if you find a source let us all know.

Just to make sure you know what I am referring to.....little black thing in middle of valve.

68Zproject... Here it is. But I can't find my pitch reader tools. I bet someone on here or TC will have one for you. Or at least tell ya the size...Hope this helps.. Danny

10-24 x 1/4".....read that somewhere, can't remember where.

Hey Chick....you are sure right about wacky.   When I click on the link it goes to post #841 at the top.  That was why I was saying I had to go backward to get to the right post number.

Crazzzzzy!!!!!

Hey Chick....I noticed that location on Danny's pictures and immediately thought of you.....just forgot to tell you about it.

BTW....the link you posted is not the correct one, it should be the two prior pages that are displaying the alternator mounting problems.  Just a thought....did you measure to see if the alternator might be positioned too far forward.  I think that when I had headers on my car, the adapter positioned mine forward. 

Just a thought.

Also, does anyone know what size the bolt is that holds the auto choke assembly to the manifold on the 68 Z?  I lost mine in the shuffle and the AIM just says production bolt.  Thanks.

Harv....this link is for an eBay ad for the screw but it shows a good picture.   Maybe you can find one locally that will look the same.

Looks like the size may be 10-24 X 1/4"

"BJ" is the identification code of the pulley that was used on the assembly line.  You showed an earlier picture of the real drums that had a "BU" sticker and the front springs had an "EE" sticker.  Same thing.
