Looking at the VIN, it appears to have been issued between end of Feb thru March '69
The tranny casting date looks to be the first week of Feb (2 + 1 dot) but a better view will be needed to make sure the dot is not a casting artifact.
It looks like the P-code is 93 XXX(can't make the rest out) so that would be March 69
So far the date periods look good.
What is the tranny case number?
Can you get a picture of the engine VIN stamp too to compare to the tranny and the trim tag?

Or maybe an internally collapsed hose, if they are old.
Sort of like how it can (and does) happen with brake hoses causing brakes to lock closed.

I got mine done by Carb Junkys http://www.carbjunkys.com/
They refinished each part to their original finish (example: goldish body, zinc colored butterfly's, etc) and they provided an 18 day turnaround and a good price.
It even had new shaft bushings installed.
It was important to me to have the correct finish on each part instead of an all gold carb + parts refinish I have seen on so many 'restored' carbs.
The only finish not preserved was the green Teflon coated shaft ends (mine were rough anyways). I used an approximately matched color enamel for those 2 small sections visible on the outside.

Tony,

  The code is usually the week number of the year and they can be found along a flat edge somewhere. Sometimes they are lightly stamped so you have to look carefully. On my hood it was on the right side edge towards the front and the fenders along the top edge that is folded to form the water channel. The door date was behind the panel.
Here is a link to more info: http://www.camaros.org/numbers.shtml#sheet

 OK...I forgot about the blackouts for the BB codes and the Z stripes. That makes sense now. So even though the codes themselves don't directly reference an engine combo but the work to prepare a body does indirectly reference what is to be placed in it when sent through the wall.
 I always thought the differences between the L35 and L78 was the the shape of the radius rod (round vs. square) but the rod evolution seems to have changed as the production run progressed and the floor plate was the same with either rod so that idea isn't valid. Otherwise I can't see any body preparation differences between the two BB's. I don't why Chevy didn't adapt the 2 radius rod setup like the Firebird.

Mike

............  None of the Fisher codes on a trim tag directly identify a specific engine or drivetrain component, they only identify extra work that was needed to be performed on a "base" body to prepare it for the drivetrain and other options to be installed by GM on their side of the plant.  4P just mean't that Fisher needed to install the front bracket for the radius rod, that GM would install later.

Hi Mark,

 Based on your comments above, why are there specific 4P thru4 L option codes listed that do define an engine option (section 4) and tranny option (section 2)?
As for the radius rod, I suspect that this may not be an engine error based on the CRG report for radius rods that states:
About one-third of L48/M35 cars have been noted with the round radius rod installed, while the remainder have the rod brackets but are absent the rod. No definite installation pattern has emerged

I have to say that this particular car research is interesting indeed.

The build sheet *may* be above the gas tank though I have never seen one myself. I found the UOIT on my LOS car taped to the tunnel on the drivers side under the carpet along with an electrical inspection tag.
I was told these are rare to find however so I got lucky to have one with my car and it's the only documentation I have to show it is what it is.

Mike

............. but cracked up at every Camaro with that dang caution sticker you referred to Marty. Who the heck is restoring these things? The more we learn the more we notice how incredibly wrong some of these high restoration.

  When I see these repeated fan sticker mistakes I often think of what Jake Holman said in the movie The Sand Pebbles:   "....pigeon see...pigeon do" 

Mike

Hi Tony,
   The casting dates look tight so that's a good sign. What are the head cast dates? Did you check the cast numbers as well to see if they are correct? So far everything looks good but it's fun to document the numbers. Per a UOIT (a document that is rare to find), that area of the plate where the engine code would be stamped is listed as the engine reinforcement assembly.
So, if Mark is correct with the traction bar plate installed vs. not installed, then that would make sense why yours doesn't have the code stamped.

So far,  based on what you have presented, it looks like the car is authentic. I guess other cars built with that power train combination would have to be sampled to make that a definite conclusion.
Do you have other documentation such as a POP?

Mike

Ahh yes...the muscle car vs. pony car debate still lives!

I have got to get me one of those fan stickers 

Interesting article though and thanks for sharing.

Mike

 Tony,
  You will also find this interesting as well:

 So the engine code shows it's a 350/295 L48/automatic and the rear shows it's a 12 bolt non-posi.
What is interesting is the trim tag is missing the 4P code.
Here is a quote from the CRG indo: "The 4P code was not used at the start of production at either the Van Nuys plant or the Norwood plant.
Van Nuys started using the 4P code on the SS350 cars in September, but Norwood didn't start using the 4P code until October. Early Van Nuys SS350 cars and Norwood SS350 cars built before October will not have the 4P code to verify that they are SS's. "
 This is looking like you car is an exception to this finding being yours is mid June 67 (Kurt?). Then again, with a VIN sequence of 666 anything is possible 

The engine assembly is March 23rd. Early for a June build but it is possible it sat that long.  Both my 67 BB's sat about 2 months before being installed.
If you can dig into the block casting dates and numbers (intake, block, distributor and even heads if you want to pull the covers) that would present a clearer picture of what you have.
The June 1st rear date range is good. Is there a rear factory traction bar on this car?
Per the CRG end of month VIN report, the160666 falls in the June period, which is good.

As you can see, a picture can show us a lot!

Mike

That's interesting and sure makes sense.
On another note, if cans were used over the distributor then is it safe to assume that the hold down clamp and bolt were also covered in over spray?

Thanks John

Mike

 I did it with my restored convertible back in the 80's when I did a chassis off restoration. I measured the rocker heights before removing the chassis to get an approximation of the clearance height needed.  When I (well....we being a few guys) rolled the chassis back in as a restored assembly after the body was painted and chassis detailed, the body was supported by the rear wheels (acting pivot point) and each rocker supported with carpet lined 2x4's on hydraulic jacks situated mid-way and slightly above the clearance height measured before. The chassis rear was supported by a heavy duty Sears mechanics dolly to support the tranny side. I used a small section of steel pipe to act as the alignment pin before securing with the chassis rubber and bolts.

Mike

You have style Marty!
 That picture is hysterical
