Some parts like alternators received an ink stamp in addition to the hard stamp part number for fast ID @ 57 units per hour. However I doubt it was done on a machine like that. Probably they were tested at the end of the line and were hand-stamped when they passed.

There are plenty of ZL1 engine photos in vintage magazines but those are likely engineering builds. The only reliable production ZL1 engine photos are of the #3 ZL1 in the August '69 High-Performance Cars. Intake fasteners appear to be zinc; the oil pan fasteners are clearly visible in one of the undercarriage photos; probably zinc. Timing cover isn't in the photos.

If it is the original pad the plastic liner is probably warped and the vinyl has shrunk. I used Weldwood; it works for a while but will lift again shortly.

Don't have engineering drawings so I can't ID it.

Air cleaner studs are application-specific; 7 different part numbers for '69.

The process worked well for parts made of soft material; ours roll-stamped copper fuse caps. Place the part in the fixture hit the buttons; the fixture rolled the part over the stamp set under light pressure. Took a few seconds.

Roll-stampers were common and relatively inexpensive. Way back when I was involved with the Camaro business new distributor housings were still available from GM so we acquired 10 or so for someone. They weren't stamped of course but I'll bet they are now. New 1111480 distributors were also still available and we had a few of those.
22  Camaro Research Group Discussion / General Discussion / Re: Vin/Trim number help 69 RS/SS 396 on: April 03, 2015, 05:53:22 PM
Thanks guys it seemed too nice and made up to me. The guy has it all mocked up to look really nice but that's it, doesn't run or even have front springs installed. He claimed it was all original sheet metal, but could tell it had qtrs, trunk and even a tail panel installed. I asked him if I could remove the back up lights to see the original tail panel cut outs but he would let me. Here is the link http://cleveland.craigslist.org/ctd/4949767386.html. I searched google last night and all he does it mock up the cars to look good them sell them. He was a really nice guy but I'm looking for a few really nice 67-69 Z28's or RS/SS 396 cars.

Non-original RS backup light holes do not indicate it wasn't an RS. My real Z/28-RS had the rear body panel replaced as did many real RS cars.

The hard-stampers I worked with in my Industrial Engineering days were fixed; the part was rolled over the stamp set.

Off-set ink stampers transferred an image to a fixed part.

Tag looks repro to me. I'd keep looking.
25  Camaro Research Group Discussion / General Discussion / Re: Is it a 1969 Z/28? on: March 27, 2015, 07:01:52 PM
That would be all 1969 Camaros ordered with U16.
26  Camaro Research Group Discussion / General Discussion / Re: Is it a 1969 Z/28? on: March 27, 2015, 01:08:40 PM
A confusion in terms.

A tachometer or special instrumentation was a mandatory extra-cost option when ordering a Z/28 as of January 2, 1969. For some reason it did not take effect until May. Jerry's '69 book has a pic of the window sticker for Z/28 N709540, one of the last built. It lists U16 at $52.70 and Z/28 at $522.40.
27  Camaro Research Group Discussion / General Discussion / Re: Is it a 1969 Z/28? on: March 27, 2015, 11:40:06 AM
Yup; any 8 cylinder Camaro could be ordered with U17 [required D55] and many Z/28s were. But they added $150 to the car. Z/28 required J52 power front discs [$64.25] and a 4-speed transmission [$195.40]. Positraction was neither standard or required; another $42.15. Throw in a radio [$61.10] spoilers [$32.65] and the cheapest Z/28 listed around $3,700.

May not sound like much today but it was at that time. Dealers had to be careful what they stocked. That's why most were low option.

From what I've seen, you can have a tach without a console, and the fuel gauge would then be front and center (where you usually see a clock)
 Very unusual setup.

If you ordered gauges/console, you got the clock front and center, and the dash tach.  Or it could be like mine, no tach, no console, no clock.  Just a speedo and a fuel gauge.  I don't see alot like this either, but I suspect not because it's rare, but because most people convert them.

The U16 Tachometer option became available later in the model year; earliest cars appeared around May '69. Chevrolet mandated U16 or U17 [gauges] around January '69 but for some reason it didn't take effect until May. U16 is rare; only 1,410 cars built with it. Many Z/28s built without either.

All Tonawanda BB manifolds were painted. Mostly fried by the time the car was delivered.

The assembled engines were not painted as normal cast iron engines but certain steel components were painted. The ZL1 engine assembly manual shows that "black engine enam" was to be used to paint the "oil pan, air inj brkt, distr clamp, frt cover, clutch fork (exposed part), torsional damper, lifting hook, exh manif, clutch hsg cover".

Normal manufacturing processing would dictate these parts were painted prior to assembly. Automotive fasteners are coated and do not need to be painted.
