Originality / Re: 1967 Z28 Block Pad Stamp
June 26, 2025, 01:08:17 PM
I have a photo of another 67 MO pad stamp, engine assembled on the same day, that I can post for comparison if it's okay to do that.

I'd like to know your thoughts on this pad stamp. I believe the stamp to be original but had it questioned at the machine shop due to deck variation of 0.02"?

There were three suppliers to Chevrolet for the outside rear view mirrors in the 1960's. Donnelly, Ajax and Standard. (Although I've never seen a Standard mirror on an original first generation Camaro. If you DO have a Standard mirror on your car, please contact me!!)



Tried to message Ed but was blocked?


Here are photos of the outside mirror on my 67 06E Norwood car. The makers mark on the mirror glass has a S in a circle and is appropriately dated for the car. The car has been painted a number of times and the mirror is on a repop gasket. Is it original to the car? I can't say it is or isn't but it could still be a data point of interest.
Here's a CRG's members words, with respect to data, that I'll refer to " If you only input what you know to be true it will only tell you what you already know."

The level of commitment by the core members blows me away. Sincere thanks for your contributions to the hobby.

Jose,


I'm sure you'll get the information you need before I'm able to contribute but I can add another reference point to this thread around mid May. I believe that my 67 console gauges 01D Los car still retain virtually all of its original interior components and I'm happy to respond to these interior questions, or others, down the road. Cheers

General Discussion / Re: LOF Glass etching

Are you looking for an etching service to date your glass or for new etched glass?


Here are 2 vendors that provide new glass with LOF logo and date codes:

https://www.autocityclassic.com/index.php?p=home


ESC appears to be considerably more extensive but includes the cost of etching. Etching is additional for the glass from Auto City.

Great to have so much technical information in one location. Thank you Kurt and the CRG.


I did notice that the 67 Order Form lists the Special Performance Package and available Plenum Air Intake and Exhaust Headers. Very cool!

Decoding/Numbers / 1967 Z-28 Alternator Broadcast Code
December 23, 2022, 12:34:19 PM
I presently have my 693 alternator in for restoration. When discussing the broadcast code, I stated that I believe it should be NL based on posts in this and other forums. I was told with certainty that the broadcast code is CB. So, I looked into it further and did find restored alternators being sold with a CB stamp as well as some photos of well-known 67 Z-28's with CB stamped alternators.


Could the issue be that CB is the broadcast code for one of the higher amp alternators?

Hoping that someone with a Chassis Broadcast Copy (production alternator) can set me straight. Cheers

The 67 Z28 looks real nice and has been restored using some Day 2 items. Perhaps this car is actually used as a road racer. Along with factory available cowl plenum and headers (not sure if these are Bill Thomas style) there is a TI module and what might be Delco race wires. The white toe hook brackets are also another race inspired modification. Interesting car, I hadn't seen photos of it before.

Those are Motor Wheel Spyders....Joe



Thanks Joe. I don't recall seeing those before. Seems that they had a 4 year production run ending in '72. Probably a tough find today in good condition like many other vintage wheels of the day. I like them.

Thanks Scott, I also enjoyed seeing the 1st Gen photos. The '67 Z-28 is sporting an interesting looking set of wheels. Any idea what they are?

General Discussion / Re: 69 Z28 oil pan, repop?

This listing states that the seller can add windage tray rails to their service replacement oil pan.

If the regular production '69 Camaro small block oil pan is externally the same as the Z/28 pan could you not remove the baffle and install windage tray rails?
I understand that sheet metal work, welding, templates and patterns would be required but it seems like a doable project if the information was available.


The production '67 pans appear to be externally the same as the '67 Z-28 pans so this is what I intend to do for my '67 302 build. So far I've collected a couple of 3-step production pans and removed the baffle from one of them although the project is now waiting for me to develop metalwork/welding skills. I'd also like to obtain more detailed information on the rails to add to the photos I've saved. From the photos I've got, it appears that the '67-'69 windage tray rails (scrappers?) are very similar.

V1122KM  stamp shows up in The Lime Book as 67 327/275 HP TH/ 4 bbl/ AIR out of full size passenger car.


I just had a look at Chevrolet by the Numbers and it states the same information as rszmit posted.

I read it as a 1967 block cast on November 11, 1966 and assembled at the Flint V8 plant on November 22nd.
I don't recognize the "KM" application code. If it was MK rather than KM it would be a 275hp engine for a manual transmission car.
For it to be a Z-28 block it needs to be stamped either MO or MP in place of the KM. It would also have the cars partial vin stamped on the pad. I'm also pretty sure no Z-28 engines were assembled before December 1966.


In order for the block to be a 295 hp 350 the KM on the Front Pad would have to be a MS, MT, MU or MV. The partial vin would also be stamped on the pad.
