Lloyd,

Here's a clearer pic of my alternator.   Hope this helps.  Unfortunately, I don't have enough expertise to comment the one you are considering, so can't add value there.

Not sure why Photobucket rotated the picture.   I re-rotated on the site, but reverts back to this mode when I add the link.   If you click through the pick, it should display normally.




Thanks for posting Hans, although your 837 has been restored certain of the characters are unmistakeably distinct and unique to the original stamping set.

Eddie, for the 1,600 mile Z/28 the caps must be painted yellow. It's unclear if the embossed DELCO and Energizer script are also to be painted yellow as there seems to be strong evidence to support painted or unpainted. Personally for a restored car I prefer painted lettering as James did per the photos he posted on this thread. It looks sharp adds color to the engine compartment and is supportably correct.

Eddie, this is the battery you want for the production date of your car, its the only repro I'm aware of that is a side terminal design and with the appearance of a Y77, just needs painting. Batteries from this company have been poorly received by the hobby however they now have a 4 year warranty which is an improvement.  I use a top post battery I bought from them that has served me well for almost 3 years (so far).

Here is an early photo of a 1969 Z/28 engine compartment that appeared in Hot Rod Magazine. You can clearly see the DELCO script is painted on the battery. The "Delco Eye" filler cap should be in the second from right (passenger side) position as shown. The photo Chick posted (originally from Jerry) is from a 1968.

Eddie, the battery I currently have in my car (below) is a repro Restoration Battery (R59).  I replaced the red filler caps with original, vintage Y series Delco caps so it has the appearance of a Y55. The give-away of course is that the terminal polarity is conventional with + positive on the left (drivers) side. On the original Y55s the terminal polarity was reversed. The second and third photos are of a vintage NOS Y55 battery that I sold earlier this year. As James noted you can see how the paint was applied on the embossed DELCO Energizer letters, showing runs especially on the large D, C & O.

Original NOS Y55








As your car is a late production, long after late April 1969, it would have been spec'd with a side terminal Y77.

Thanks for the input. I'm looking for constructive input on the the "7". Does anyone have an original with the same digit / character shape?

37  Camaro Research Group Discussion / Originality / Re: 1100837 Alternator Stamping - Original? on: November 01, 2013, 02:00:26 PM
There is another 837 alternator on Ebay #251370450530 with the same date to do a comparison.

Dates are 1 month apart.

Lloyd - just a word of caution on "837" alternators - I had to source one for my Z last year.  I really struggled to sort out real from the fakes.   It takes a real pro to know is what I found out.   Fortunately, Jerry MacNiesh was rebuilding my engine at the time and I was able to get his confirmation the one I was considering was real.   I think he rejected 90% of the ones I sent him for consideration (at least 15 - 20 samples).   I was quite shocked how many re-stamps are out there.  

Heres the one I bought, confirmed by Jerry as a real "837".   It's a little early for my build (March), but within the acceptable range.   Also, I'll take a better pic if needed.




Yes, I agree with your comments Hans.  I have seen plenty of 837 stamps and the impressions are most all inconsistant - they were hand/gang stamped for identification and not for artistic merit.  On your 837 the bottom of the 0s (zeros) appear irregular and the foot of the first number 1 (one) is mis-stamped, typical irregularities found on others.  I have been paying far more attention to the condition of the aluminum case on un-restored orginals as its extremely difficult to fake / replicate 45 years of patina so tampering is easier to detect.

Would appreciate opinions as to the originality of this 837 stamping:

The instrument panel molding shown is currently listed on eBay with the indicated CPP or CCP marking on the reverse side. My original has the GM PN# embossed.

So did the whole production run of 69 Z 's come with the 660 only? maybe i have the wrong one...
( I am not in front of my car just trying to zoom in on a picture of mine, hard to see if it has it or not)

There is a good CRG thread on the 660 thermostat housing that might help:  http://www.camaros.org/forum/index.php?topic=10971.0

A couple of photos showing some of the differences between the original and reproduction brackets. I posted more photos and description on TC.

...never mind, I re-read the thread and located the link for the tube insert in a previous posting. Thanks.

In NCRS Corvette Flight Judging, there's only a very minor token deduction (3 points out of 4500) for use of the reproduction T-3 headlamps instead of originals, due to the night driving safety issue (original T-3's don't throw much more light than a kerosene lantern); originals also tend to "smoke and die" without warning, resulting in deductions during Operations judging.

"original T-3's don't throw much more light than a kerosene lantern"...funny.
