Just wondering When the factory was assembling engines, was it possible to have parts that were cast a couple of days before being attached to the engine. I have a 215 head with a date code of I 19 7 (Sept. 19/67). Engine built on Sept. 21. Other head casted H 2 7 (Aug. 2/67). Thanks in advance for your opinion.

 

Yes, very common.

 

Let's see.... Was it remotely possible that a Central Foundry casting was produced in one division site; the casting was shipped and received at the engine factory; the head was machined and delivered to the factory floor; the engine was assembled 2 days later?



Mike, that's even a stretch for your imagination.

 

That's true- you've seen all, know all. Keep forgetting.

 

We all got a good laugh at that one, Mike. And, not with you, BTW...

 

Hey Rick, I had the same concerns with my car , very close dates ,
I too thought they were too close for comfort until reading you post.
Ill have to sit down and get them all together , then we'll confer.
Sounds like our cars weren't to far apart on the line.

Did you get my PM with email.?? this morning.

By the way,, what's your Block dating....??


Marty,....

 

There's been many documented cases of close dates- including engine block casting dates and assembly dates only 1 day apart. I'd tend put more faith in those type of things than engines that are at the far end of the spectrum closer to six months.

If nothing else, this sort of info (easily available at the dreaded other place) keeps some people with blue cars amused.

 

Good morning, gents.

Was it true that the foundry where these parts were cast was in close proximity to the engine plant???

 

In the case of the Flint plant, yes.

 

Mike - so the Tonawanda plant - no (???) Thanks.

 

Tonawanda, I was not sure of actual distance. I see that John Hinckley has stated on the other site that the physical distance at Tonawanda was 100 yards apart and that that your two day spread was possible.

The distance at Flint was a half hour drive IIRC and there was a fleet of dedicated trucks moving stuff almost non-stop.

Wonder if the blue car guy is still laughing?

 

Thanks for the info - much appreciated.

Regards BK3

 

Pure baloney. Having a part cast on one day, transported, machined into a finished cylinder head, moved to the assembly line, and being assembled into a completed engine ready to go out the door within 2 days is a total pipe dream.

Now, could an NCRS person contrive a scenario in which that can actually occur SO THAT HIS CAR CAN BE VALIDATED AS A [POSSIBLY] FACTORY-ORIGINAL VEHICLE? Sure. That's what someone with a 'special interest' would want to happen.

No one with any familiarity with GM plant operating systems and metal fabrication would be goofy enough to believe this could happen. But, if the dogma states that any date earlier than the vehicle build date is viable, that MUST mean that it's the absolute TRUTH...

These are the kind of things that go on which prevent me from having any interest in the NCRS organization. "Legitimacy" of a vehicle is decided by some "expert" in the organization and then perpetuated ad nauseum "because he said so"....rather than just setting some basic standards and then appreciating the many Corvette cars for what they are.

 

While I think of it, there's a post on the other site written in November 1998 by Al Grenning describing how it was possible for castings to end up in finished engines in such short time periods. This set of circumstances was confirmed by a former GM plant employee named Phil Hawkins who separately described why some castings also sat around for months.

That makes two different guys that were 'there in the day' who confirmed how and why. The independent modern day research by Al Grenning to find out why so many 1-2 day spreads showed up on undisturbed cars is typical of his thorough investigative work.

Coming from a manufacturing background myself, I can identify with the logistics that were involved 'back in the day' that caused such variability.

 

And why did someone go to the trouble of finding some folks who worked in those plants 'way back when'? Because someone in NCRS had a car with some heads [which didn't come on the car] that were CAST two days earlier than the engine completion date! So, there is an 'agenda': find some folks who were there and have them confirm that "It was possible". And that's what was done.

Does that convince me that it could actually occur? No, not for a heartbeat. Hidden agendae get "proved" all the time...by whatever means are necessary.

 

"WOW" Bk , stirred up a hornets nest here , didn't you?

Not a pipe dream. Entirely possible. Dig out your old copies of Corvette Enthusiast Magazine and read John Hinckley's article on small block production at Flint. They cranked out and shipped an average of 5500 engines a day.

 

Keep in mind that the guy with the blue car said just a few days ago that he doesn't hate the NCRS:

Ya right.

Let's consider two factors

1) NCRS doesn't judge date codes on heads at all. They're underneath the valve covers which are not removed.

2) NCRS doesn't authenticate any component of a car as being 'the original born with' piece.

So there would be no incentive or benefit for a member to invent a story about date codes or engine assembly process.

Also- the OP and the other gentleman in this thread whose cars have close dates have not (yet) been through the judging process or been otherwise desecrated by the evil NCRS. Add this to the hundreds or thousands of cars that have been noted over the years to similarly have close dates.

I wonder how this can be explained- who are all these people that choose close dates, why would they do so if it's controversial- and possibly most perplexing- where do they find these stack piles of parts that are dated so close? Seems to me that there would be an even bigger stack of components that are dated much more realistically, up to six months older than the assembly date let's say. If I were building a clone car to fool someone, the LAST thing I'd do is make fundamental mistake with obvious stuff like this.

But there again, I'm not very good when it comes to imagining conspiracy theories. I've misplaced my tinfoil beanie, so maybe my brain was reprogrammed while I was sleeping.

 

Why would someone bother to research it, if it didn't matter???? Why would there be some article in a magazine, if it didn't matter????

Just more one-sided speil...
