286  Camaro Research Group Discussion / Decoding/Numbers / Re: Rear axle tube codes and engine codes on: August 09, 2011, 06:09:18 PM
Hugger....the numbers from your POP are build numbers.  Listed below are the numbers decoded.

     Engine
          T -Tonawanda engine Plant
          05 - Month of build
          22 - Day of build
          MN - Engine code (Special High Performance 427ci)

     Axle
          BE - 4.10 Positraction
          06 - Month of build
          10 - Day of build
          G - Detroit Gear

That's the wire that goes to the back of the alternator. The tab is embedded in the wiring harness.
oneZ11.....Do you have an AIM?   If not, then you need to get one and examine it front to back until you nearly know it by heart.  That is the first thing I did and it in turn answered numerous questions that I had about the Camaro assembly process.

Marty....AIM, UPC 6, Sheet B9, View C (Left side is screwed together),  View D (Right side is spot welded together).

That indicates that both are correct depending on what side they are used on.

Also according to most accounts, the left side bracket that bolts to the block was attached to the block at paint time....thus the bracket was painted chevy orange as well as the bolt that bolted it to the block....the rest of the bracket was added at the engine dress process.....actually if you look closely at the View C it even states that the bracket and the bolt was part of the engine assembly.  The right side was added later at the engine dress process and none of them were painted as well as the bolt that bolted it to the block.

Now this is the 1968 engine I am talking about....I am not 100% sure that this carried over into the 1969 engine line though.  Maybe some of the 1969 people will know more about this.

This make sense.....?

I agree, and the original "30-30" cam is what gives the Z its distinctive character.
X2....Wouldn't be a Z without the "30-30" sound.

You might try this link and see what the quality looks like first hand:  http://www.scribd.com/doc/32913817/69-Camaro-AIM
291  Camaro Research Group Discussion / Originality / Re: 1967 Small Journal 350 on: July 28, 2011, 04:27:07 PM
According to all my sources there was only one 1967 350ci crankshaft and the specs are as follows:

   Rod journals   2.10 - otherwise known as the large journal  (Small journals were 2.00)
   Main journals  2.45 - otherwise known as the large journal  (Small Journals were 2.30)

This information was taken from the reference book entitled CHEVROLET By The Numbers written by Alan L. Colvin

So therefore there was not a crankshaft made with mixed small and large journals....they were either one way or the other.
292  Camaro Research Group Discussion / Originality / Re: 1967 Small Journal 350 on: July 27, 2011, 10:25:29 PM
Now that is strange....why would there be a crankshaft with large rod journals and small main journals.  About the only way that would happen is if they had a large journal crank with bad main journals and they then ground down the mains to the smaller size and stuck the crank in a 327ci block.  That would be a one of a kind animal.
293  Camaro Research Group Discussion / Originality / Re: 1967 Small Journal 350 on: July 27, 2011, 10:08:16 PM
You only mention the main journals as being the smaller size.  How about the rod Journals?  Are they they the smaller size also?

Also I checked my July issue of the 1969 GM parts manual and there is only one part number for a 1967 & 1968 350ci crankshaft.  So if they ever did make a crankshaft with a small journal they never expected to replace it....they would have to replace the whole short block instead.

As to the engine pad.....did you repaint the pad when you rebuilt the engine?   The original engine pads from the factory were never painted.
294  Camaro Research Group Discussion / Originality / Re: 1967 Small Journal 350 on: July 27, 2011, 09:42:40 PM
What is the casting number and casting date of the block?
295  Camaro Research Group Discussion / Originality / Re: 1967 Small Journal 350 on: July 27, 2011, 03:46:23 PM
Do you have the casting numbers located on the crank?  Do you know for sure whether it is forged or cast? 

Also, you mentioned that you rebuilt the engine, did you send the crankshaft out to a machine shop?  If so, did they turn the journals?
296  Camaro Research Group Discussion / Originality / Re: '69 Quad Carb, correct linkage on: July 27, 2011, 12:25:26 PM
Update to my original reply....here is a document showing the return spring attachment.

     
297  Camaro Research Group Discussion / Originality / Re: '69 Quad Carb, correct linkage on: July 27, 2011, 09:50:49 AM
Update to my original info.  Here is a link to a better photo of the throttle rod:  http://www.parts123.com/parts123/yb.dll?parta~showpic~Z5Z5Z50000358f~Z5Z5Z5FCAHW~Z5Z5Z51~Z5Z5Z5~Z5Z5Z5

Here is a link to a photo of the accelerator spring bracket:  http://www.parts123.com/parts123/yb.dll?parta~showpic~Z5Z5Z50000358f~Z5Z5Z5FAQYR~Z5Z5Z51~Z5Z5Z5~Z5Z5Z5

Both of these can be found at:  http://www.parts123.com/parts123/yb.dll?userwatch~dynamicSearchPage~cadeiije#1967-69%20Camaro%20Parts

I can get you a diagram of the spring attachment area but it will have to be later in the day....have to go now.
298  Camaro Research Group Discussion / Originality / Re: '69 Quad Carb, correct linkage on: July 26, 2011, 06:27:40 PM
First check out this link to see if the throttle rod you have matches this one....http://www.heartbeatcity.com/store/product/13679/Camaro-Throttle-rod-assembly-327-350--68-69/
The Gm parts manual shows that the correct part number for the throttle rod is #3923539 and this Heartbeat City description states that their rod is an exact reproduction.

For the connection of the return spring....see the Heartbeat City description also.  If you don't have this AIM as they described....it shows the return spring is connected to a separate bracket, part #3930791, that is bolted on top of the coil mounting bracket base.
299  Camaro Research Group Discussion / Originality / Re: 302 Rocker Arm Nuts on: July 22, 2011, 04:04:36 PM
can't see them under the valve cover so I would not lose sleep over it. I would assume they used both designs.
Just to show you how this could be true about using both designs....I have an original '68 Z28 and the engine has different exhaust manifold bolts on different sides of the engine.  Apparently the bolt bins on each side of the engine had different bolts in them and the assembler installed whatever was in the bolt bin.  I also have seen different bolt numbers installed on the body assembly other than the ones called for in the AIM.  So either the bolt bins had the wrong bolts in them or the assembler installed whatever he grabbed out of the bin, regardless of the number.

So....as  Forrest would say "Life is like a box of chocolates...you never know what you are going to get".  I think that might describe the assembly line at times.   Roll Eyes

See this link.....http://www.amkproducts.com/Catalog_PDF/151-164.pdf.  Look on page 159 for B-10702...this is the  clip that holds the weatherstripping to the radiator support.
