Originality / Re: Correct starter brace for '68 small block ???
« on: May 18, 2018, 12:48:28 PM »
I wonder how many of those are in the landfills. I have changed starters in several Chevys I have owned over the last 45 years. All of which were used when I bought them. None of the starters I changed had the bracket. It was always left off by whoever preceded me? It's an important item. All the extra cantilevered weight of a starter without the brace hanging there definitely affects its operation. If you do an experiment and compare the sound/operation of the starter with and without the bracket, there is a dramatic difference.

Where did you see the VIN on the 2nd one? I couldn't find it in the pics?  ???

You need to hook up an accurate gauge to see what it is actually running.
And the factory gauge is not....

Second that. If you want to see a quality gauge in action, go to Jerry M's website, There's is a video near the bottom of him making a 1/4 mile pass in his 67 Z. The oil pressure gauge is pretty easy to watch in the video.

Just so I have a better understanding, if a Camaro required the quarter louvers, they were installed by Fisher? Did the stations (I'm assuming there was one on each side right and left) installing the louvers also have a tool/jig for punching the holes required, or did that happen earlier in the process? Unless the hole punching/louver installation was done at the same time, it would require an error to be made at 2 places on the line in order for a car which was required to have louvers to end up without them.

Is it possible that a car could have been ordered by a dealer with special instructions to have the louvers deleted?

So there are Z/28's with back up lights in the tail lights, non RS, and Z/28's with back up lights in the tail pan below the bumper, RS. The same with all other Camaro's, 67-69.

Known to you if you collect the data yourself.
I don't think the CRG intends to publish any data points on motors or any other part, as to not help the fraudsters.
I have gotten better at spotting fake trim tags, because I have started collecting images of real ones from certain time frames. So if I find a questionable Camaro, I usually post it on the CRG with my suspicions about the tag. And usually someone confirms my suspicions. So CRG likely will not post "here are all the good dates..."
But they will rule out or will give their opinion on anything questionable.

Not exactly what you may be seeking, but it is still an aid.

I don't think all the info the CRG has, needs to be so guarded, but still plenty of fraudsters out there that will restamp, or try to make an extra dollar off a dummy.

Maybe I have learned more by them not coming out and giving more info.

I am not seeking anything other than a better understanding of the whole manufacturing process. I understand perfectly well that CRG would not be giving out this type of data for obvious reasons. My point is that as more and more data points are added to the CRG database regarding 302 engine build dates/stamps the tougher it would be for fraudulent engines ( and Cars) to pass a CRG inspection. And that would be good for everyone. (except the forgers)

So in the CRG data base of Z/28's, 302 engines, if enough data points were observed, there would be a pattern of dates that the 302 was produced, and also a pattern of pad stamps for a given batch of engines. And then it could be determined if a pad stamp was legitimate based on the date and the pad stamp. Same as when a distributor stamp is observed, and someone comments that it is a "known good date". If that's reasonable, then I guess the next question would be: Are there enough data points in the data base now that allow for these patterns to be known? If so, it would make faking a block very difficult for anyone without the data base or knowledge of the patterns. At least if their forgery had to pass CRG inspection.

So I understand that Flint was capable of producing every combination small block required during a typical production year. My question is, Did Flint produce a particular engine configuration in batches? Eg, would the 302 have been produced in batches of say, 100 at a time? As opposed to a random production sequence where every different engine produced could be a different configuration. It would seem that this batch approach would be a more efficient method?

The speedo gear was matched to the specific vehicle long after the tranny was assembled so no need for a different part number.

So when was the speedo gear installed? On the assembly line? So was it called out on the chassis broadcast sheet?

I'm sure the occasional wrong part got installed, but it seems like a lot of it these days is people trying to convince themselves they have something they do not using the assembly line error argument.

Correct me if I'm wrong, but I believe the carb would have been installed at the assembly plant, Norwood? So date wise, it's not directly correlated to the engine build date. Could be before or after, I think? But obviously before the car's assembly date.

Should be 68 builds, and would not have an X code on the tag. The only info which can be deduced from the tags are engine, (V8) , paint color, top color, and interior style/color. What are the VINs?

I was under the impression that it was needed for the assembly line for operations occurring before the trim tag was even installed.

I know 20,302 seems like a lot of cars, but back when they were new, you didn't see Z's too frequently. Yes, they were around, but there seemed to see a lot more SS's, and especially the SS Chevelles. They seemed to be everywhere. At least those are my 50 year memories.

Have you removed the interior panel by the quarter windows and checked the quarter from the inside for original holes that may have been filled? I know you stated there was no evidence of any. Is that looking from the outside? Just an idea.
