Anybody out there with information on big block timing covers?  I might have a chance to dig through my parts this weekend and find a couple of examples to compare to others if posted.  Thanks to all who have commented to date.

It sure looks like the small blocks are trending toward the week of production and year.  "3 68" would be 3rd week of calendar year 1968.  Could big blocks use a different format?  Kurt mentions a letter in the mix.  Was that for small block or big block?

Looked through all the threads on this subject and could not find a definitive set of guidelines for small block vs big block timing cover date code format.
So far the codes are supposedly week and year of production i.e.  21 69 is 21st week of 69, Julian calendar date vs year i.e. 21st DAY of 1969 or even MONTH of production vs year.  It also appears to vary from small block to big block . Can any of the guru's here summarize what the latest tribal knowledge is on these date codes?  THANKS...

Agree with the theory about removal for drag racing.  I bought a z-car years ago that was set up the same way for drag racing.  It was a bear to stop so I replaced the booster so I could drive it on the street.

Thanks for all the feedback.  After considering all of the input from folks online here and shooting a test panel I decided to pull the trigger and use the Black-it.   Wet sanded and prepped the firewall and shot it in thin coats.  Results were great as soon as it flashed and after a 24 hour cure time it looked even better.  The first test area must have been a fluke because it had more gloss than the prepped and shot firewall does.  Now on to the trunk...

  I assumed that the original black out had oxidized since it was sprayed, but there is still a notable difference when compared to the BlackIt product.  I have to finish wet sanding the firewall before it gets painted anyway so I can monitor this post for a few days before I get into the job.

BTW: Don't anyone get out of shape over the "experienced opinions" statement.  I was looking for some folks that had recently dealt with a like situation and determined a good plan to get the firewall close to an accurate finish.  No sense in reinventing the wheel.  Getting JohnZ's perspective in the mix was a bonus. 
Thanks for the replies and keep them coming.

Looking for experienced opinions on firewall blackout paint.  Percent gloss, manufacturer, aerosol preferred.  Was going to use the OEM BlackIT Poly black in eggshell finish on my resto car.  Problem is when I inspected my other unrestored 69 the paint looked almost dead flat black.  Tested the mentioned eggshell OEM around the heater motor area on the outboard face of the cowl and there is more gloss than the original finish.   I assume there was some variance in the gloss from the factory but I want to get this right and not too glossy.  Any help would be appreciated. Thanks...

FWIW:  My 04C Z10 and 12 B RS/Z both have park lamp lenses with stainless trim and argent silver paint.  Paint can't be seen from the front of the car so if you were not specifically looking for it you would never know.  Thought it was overspray or something added by an "artistic" past owner until I looked at the other car and they were both painted.  As such there may be more survivor/low mile cars out there with these lenses than what is currently assumed.

G-r-e-a-t.... Sounds like the Barrett-Jackson crowd is jumping all over the Z10's.  Another car that the working guys can forget about picking up.  If these prices are real I'll be less likely to drive mine anywhere and leave it out of sight.
25  Camaro Research Group Discussion / Restoration / Re: 1969 ss 350 x55 code on: July 28, 2006, 02:02:32 PM
For what it is worth...I owned a 69 SS350 with Muncie that had a 318 block assembled on 5/17/69.  The body tag was 06A.  Bought the car in 1975, so there was little chance that someone tried to clone or re-stamp the engine.  VIN on oil filter boss matched the car.  Found it when cleaning/detailing the block prior to rebuild in 1977.  Car was sold shortly thereafter to provide funds for college.    Could have been that a few 300/350's were stashed at the plant and installed late?

  Thankfully someone DID recognized the significance of the building, although it was not saved entirely.  I only recalled the demolition crew uncerimoniously tearing it down into a pile of rubble.  Only thing left now is a concrete slab and some weeds emerging from the cracks. 
  BTW - Wasn't Werner the owner of a one-off GM Design exercise C1 at one time?

John: You may recall the sister facility about 1/4 mile north of the old V-8 plant was the birthplace of the early build '53 Corvettes.  It was demolished within the last several years as well.   Not even a brick was saved.  No plaque...nothing.   Sad....
29  Camaro Research Group Discussion / Originality / Re: Engine casting date vs build date on: May 08, 2006, 03:58:45 PM
Entirely possible for casting and assembly date to be the same.  Between the two of us, my father and I worked at Chevrolet Motor Division on Van Slyke and on Chevrolet Ave (Flint, Mi) in the 60's through the early 80's.   So we witnessed the operating tempo of these facilities during the height of Chevrolet success.  Raw engine blocks were trucked in from Saginaw Foundry around the clock in stake sided heavy duty six axle semi trailers.  Operations were running on 3 shifts, 7 days/week for months on end.  With that rate of volume, coincident cast/buld dates would not be a surprise...

Hey there:
Handle on the old forum was Z10Mike, and still Z10Mike.  Thanks for the heads-up...
