All engines had what would ultimately become the stamp pad suffix scrawled on the side of the block in grease pencil; that was done in the first operation on the engine assembly line, where the block was upside-down and the bores were air-gaged. That marking told everyone on the line what innards and external parts to install in the block (cam, crank, rods, pistons, oil pump and pickup, pan, balancer, lifters, heads, intake, water pump, valve covers, distributor, etc.). The pad didn't get stamped until the engine was turned right-side-up and the heads went on.

Mine is a phosphated Grade 5 (3 lines) bolt with traces of orange overspray (02D '69 Z/28).

215/65-15 is exactly the same size as the original E70-15.

Wheels are incorrectly painted, and wonder why they put the washer bottle in the RS location?

It's a lot easier to just upload images directly from your computer - use the "Choose File" button below the window you type in, and use "more attachments" if you need to upload more than one image (you can upload a max of four per post), and each must be below 150KB.   Smiley

I live a half hour from Temecula and did not here about the Rod run this time, otherwise I would have brought my Turbo Rocket there!

Very cool! I haven't seen an Olds F-85 Jetfire in years!  :-)
22  Camaro Research Group Discussion / General Discussion / Re: 67 convertible 6 cyl 3 speed rare?? on: March 15, 2014, 10:51:52 AM
Question, do the numbers match on the cowl tag begin 124 and the door jamb tag begin 123? As I understand vin 123 is 6 cylinder and 124 is v8 or am I confused?

Remember that the "Style" number on the cowl tag and the "VIN" number on the hinge pillar or instrument panel are two COMPLETELY DIFFERENT numbers; the "style" number on the cowl tag was assigned by Fisher Body, and it will change on 67's as noted above. The VIN number was assigned by Chevrolet much later in the process, and a "3" for the third digit will ALWAYS mean a six-cylinder engine, and a "4" for the third digit will ALWAYS mean a V-8 engine.
23  Camaro Research Group Discussion / General Discussion / Re: Is this tag real or fake? on: March 14, 2014, 02:03:26 PM
According to the Camaro Expert in NY the car is genuine.. 

It may be "genuine", but it's far from "correct" - LOTS of missing/wrong parts and processes. :-(
24  Camaro Research Group Discussion / Decoding/Numbers / Re: Correct Striping on: March 11, 2014, 09:45:03 AM
Others have commented that
the assembly manual is wrong, but with no supporting evidence.


We've known for many years that the rear stripe illustration in the Chevrolet Assembly Manual (section Z28, sheet B2, View "A", 5.20" dimension) is wrong; Fisher Body didn't use the AIM - they used their own Operation Description sheets ("O.D. Sheets") and Release drawings from GM Styling to create the stencils used in production.

Here are the original door and quarter window fuzzies on my unrestored '69Z.
26  Camaro Research Group Discussion / Originality / Re: 327 L30 Intake Manifold date on: March 10, 2014, 09:03:47 AM
Q for the group:  Would a casting date of "I86" (Sept) on the intake manifold of a '67 11A LOS  L30 build be too far out of range?
Looking to determine if I have a transplant.

It's a llittle beyond what's "typical", but certainly not out of range; if it was on a Corvette, it wouldn't get any deduction in NCRS judging.
27  Camaro Research Group Discussion / Decoding/Numbers / Re: 302s and CE Blocks on: March 06, 2014, 01:14:04 PM
All factory replacement and "CE" 302 small-blocks came from Flint V-8; Tonawanda didn't have the forged 11:1 pistons, "pink" floating-pin rods, "30-30" cam, solid lifters, 1178 crankshafts, and didn't have 2.02"/1.60" valves or the machining stations for them (including the unshrouding cut adjacent to the intake valve). Tonawanda only built hydraulic-lifter flat-top piston small-blocks with 1.94"/1.50" and smaller valves.

Tonawanda was the sole source for big-block engines.

Here's a photo of a similar pinstripe fixture in use in 1965 at the Pontiac home plant - it has suction cups to hold it in position, and the top rail is the guide for the tip of the Beugler roller-striper. Two different Beugler guns were used - one with a thin roller, and one with a thicker roller for the second stripe. The Pontiac fixture is being used in an off-line stall, but the Camaro pinstripe fixtures were on-line, suspended from overhead balancers, and moved with the car.

Go here for more detailed information on the Beugler striping tool:

John,  Would you have any idea if the 'exclusion' might be something that could be 'Deleted' via a customer order form (for a Z28 buyer who wanted the pinstripes)??

As far as I know, there was no mechanism to let a car order override the programming of the Body Broadcast; when a Z/28 was ordered, it automatically defeated the broadcast code for pinstripes.

That's a gorgeous car, and I too have always loved the minilite wheels.. Smiley
Re the fender stripes:  I think I recall seeing some original GM Z28 ads which showed the 'over wheel pinstripes'... 
Was that, or was that not, an option?

The fender pinstripes were part of Z21, but the pinstripes were specifically excluded when Z21 was ordered on a Z/28.
