1  Camaro Research Group Discussion / General Discussion / Re: HELP!! I need info regarding original exhaust DB level!! on: July 29, 2014, 10:25:18 PM
Hey thanks Pacecar!

I know of gardner and tought about it... The thing is, id need to be able to prove it was available as an option on EVERY single Camaro in 69.



Aside from the chambered exhaust, what was the orig exhaust like on a 69? Something like my American Thunder (Flowmaster) system layout?

Thanks for the help!!

Lead.
No single exhaust system was available on every single 1969 Camaro optional or otherwise.

RPO's L34,L78,L89 & Z28 produced before Dec 4th 1968 used a chambered type exhaust.

As of December 4th the Z28 went to a single crossflow muffler until May 2nd when resonators were added in front of the crossflow.


I would go buy an old original system that was worn out and put it on... If they want GM part numbers it would have them.
Call GM and tell them your Canadian overlords have dictated they sell you an original system, seems to be a catch 22, you have to have it but you can't buy it..
Seems to me that if it's not available it is difficult to require it's installation.

I too have wondered about the cleaning very well and applying silicone to  the tags and rivets front and back so there is no possibility of them contacting the solution.
IF I HAD TO REMOVE/REINSTALL A VIN for a Customer, they would be required to sign off on the fact that they requested the removal and metal replacement and that they understand the value could be reduced and it's authenticity may come into question. I would fully document every single thing I did on HD video, including the reason, showing other hidden VINS and showing the metal work required and then the REINSTALLATION, I would keep a copy of everything to cover my ass in case there were ever a question or he said she said episode.

If doing any blasting I use multiple layers of Gorilla Tape over tags.

I have seen people try this method before and never once seen it work.
I suspect a lot has to do with the original impact of the characters and the depth of the milling.

Take this with a grain of salt as I haven't ever seen it done, however the engineer stated that "you couldn't grind enough metal away to get rid it without ruining the block".

Blue is coolest I expect, if so then there is no deep radiating heat and the pad itself is not 100 deg, correct?
I think there are faints of some characters the way it was described to me was the engine needed to be brought up to temp then the pic every 10 or 15 min through cool down. The heat cycle will be completely different and hold longer vs heating the pad directly, maybe a rosebud on an oxyacetylene torch working in large circles under the pad.
If you had a industrial parts washer for cleaning engine parts it may work since the block is completely heated, hell leaving it outside one afternoon around here would get it 120.

Sounds like Dave Miners old car but his had just under 10k and was not a RS.




I hope to see this one come out a garage... get it!

Those are GREAT pictures!

The double tap on the Z also leads me to believe it is real.
I read a metallurgical engineer's statement recently that using a thermal imaging camera on a tripod, start the engine, allow to come to operating temp, then cut it off, take a pic of the pad every 15 minutes and the original stamp will appear. Said that you couldn't grind away enough of the pad to get rid of it and still have the block useable. I'd like to see if this works... anyone have a TI camera?

I have also heard that someone in OH has a REAL BROACH as big as a locomotive is how the guy I talked to put it.
He was asking me about having a block done, I told him there is no way they are going to be able to get the broach to make the same tooling marks as originals... machines scraping metal away wear and the wearing will happen consistently, the broach marks from one month to the next will progressively change, approximating the change will be NEAR impossible given the number of legitimate broach photos on file with people who check and certify high end cars.
Someday we are going to cut out all this nonsense... I read recently that the vette guys are at least 10 years ahead of any other marque on being able to identify fake tags and stampings.

Was that the UOIT? or something else?

It is not consistent with other tags of the same week, I have a bunch of tags from the same timeframe as this one and they don't have the same characters style on several of the numbers.  So yes I would say it is a repro.  The body number is also probably the original number though.  No telling what the car was originally now, was it just a color change on a Z, or was it a base 307 coupe.

X2 I came to the exact same conclusion...bad characters but body num was prob original.

This may be another point if so admin please move to appropriate category.
Referencing Camaro Assembly Process auth -JohnZ
specifically Vin Assignment.

Once Chevrolet received the bodies from Fisher, (1 VIN)the Chevrolet scheduling rules and priorities took over, and that process was managed by the Body Bank operators, releasing units (or 2 VIN) into the Chevrolet assembly system based on proper labor line balance and option workload distribution.

John where exactly was the vin assigned?
1. immediately upon receipt numerically in order from Fisher or
2. after being scheduled and released into Chev Assem based on line balance etc?
3. other

Yes Mark something does look off there...

100k no smog or manifolds that'll run $2000 ouch! I saw the Tail light lenses (x77 didn't have vertical stainless trim), however the correct ones are not reproduced. Reproduction interiors just look too plastic to me.
Really a very nicely done car if the numbers checked out as legit...

I've not too big on red cars since I was a teenager but I do like Garnet red when it looks like that one!

It's really not a semi gloss, Here is an untouched unexposed place on a 69 SS showing there is a reflection and a good bit of gloss.

Here is Elkhart Lake with a 68 Z (stock) with 4 68 Camaro Conv's The 68 Camaros look to be a mix of RS/SS's and Std SS's the interior color is lighter than black would appear as does the hockey stick in other photos...
