Decoding/Numbers / 1967 Z-28 Alternator Broadcast Code
« on: December 23, 2022, 05:34:19 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

I'm not sure what to make of this transmission's assembly date code. Decoding it is straight forward enough but, as I understand it, the 660 case was introduced for the '68 MY. Is it possible that this transmission was assembled July 7th for a '67 MY car as indicated, perhaps as a warrantee replacement, or is more likely that either the assembly date code is an error or re-stamp?


I'm wondering if there are any other examples similar to this or if anyone has opinions on the authenticity of the assembly date code.


Thanks for any input your able to provide.

Decoding/Numbers / CE Block, Flint or Tonawanda?
« on: November 07, 2021, 08:21:37 PM »
I have a CE block that I'm considering using for a '67 302 build and have realized that the sequence number falls into the Tonawanda assigned range base on the Chevrolet Dealer Service Information Bulletin, 69-I-1,dated 19 Sept,1968.[size=78%] [/size]Other indicators point toward this block being cast and assembled at Flint such as a square-head 1/8" NPT plug and assembly date stamp including a "V".



Here is the block information:
Casing number: 3892657
Casting date: J127
Pad stamp: CE8 54915
Assembly date: 10 7 V


This block was cast and stamped well before this Service Bulletin was issued, provided that the CE stamp is legit.
I would like to know if there are any other similar examples out there and if this block indicates that there was a different assignment of sequence numbers used prior to 19 Sept,1968.


Thanks
Terry

Decoding/Numbers / 1968 LOS 04D L30M20 POP Error?
« on: May 29, 2021, 10:06:08 PM »
We've had our 68 Camaro for more than 10 years now and when we purchased it it was being represented to us as a L30M20. I do believe it to be an original L30m20 and the POP mostly supports this except for the transmission code. The issue is that the POP indicates the transmission type as "S" Saginaw 3 speed. I've read about POP's containing error's and am interested to know what CRG members thoughts are on this particular car.


Here are the cars vitals and numbers photos:

1967 Z28 original ad from Dec 4, 1966 (camaros.org)


I opened this post with considerable interest only to find that the Tiny Pics attachment was no longer available.

I'm wondering if anyone has saved it and would be willing to post it again.

thank you

1968 - Orphans / 1968 MO Block 18N424982 V0423MO
« on: May 04, 2021, 03:22:37 AM »
I am interested to know if the car still exists and I am open to reuniting the block with the car. The block currently resides in my engine bay so a reunification would need to happen on a schedule of sorts.
VIN 124378N424982

Originality / Block for 1967 Z28
« on: May 02, 2021, 10:53:39 PM »
Hi CRG,
I'm a long time 1st Gen owner and have relatively recently acquired my first Z28. The car came with a 68 MO bock in it and my intent is to build a 67 302 for it.
I've located a 3892657 block with a casting date of E177 which I believe to be appropriate for a 06E NOR car although there seems to be a wide range in block casting dates used, with perhaps some months omitted, for Z28s produced at this time.
I'm trying to determine if this block has been decked or if this block could be a warrantee replacement or over the counter block with a blank pad.
All comments are appreciated!
