The L14 (307/200) replaced the LF7 (327/210) on January 1st, 1969.

I know the date but didn't know what that meant as far as the engines istalled in the cars. Seems like for there to be 01A 307s the notice would have had to gone out early enough that dealers would know what engine would be in the car they ordered. I would have thought a date deadline would have been that any car ordered after a certain date would get the new engine.  I mean how would they know how many 327s to have on hand if they were going to start putting 307s in on the first workday of JAN?
What would have been the leadtime on order to build to ship dates for a base car in this timeframe?

I have been asking the same question regarding my '69 RS since Nov 1991 when I purchased it.  Although it has the original Powerglide and rear end, it did not have the original engine in it when I purchased it.  The fenders were (and still are) badged 327.

Since I don't have any documentation the assumption by most (including the CRG database) is that my car (Norwood, 01C build) left the factory with a 307 and not a 327.

Shortly after I purchased the car, I was able to track its history back to 1982 and know that in 1982 it was as I purchased it in Nov 1991 -  327 badges and all.  (Obviously someone back in the day could have changed the fender badges.)  

A few years ago, I tried comparing BDY numbers from the trim tags of various cars against mine to see if there was any sort of a trend.  I havenít looked at this information for a while now, but your question reminded me of it.  Previous posts to this forum remind us that the body number was assigned at the time of order.  Build dates were assigned when the car body actually began to be fabricated.


From the 11 NOR trim tag body numbers that I have collected (not enough for a good statistical average, but a start nonetheless) I have the following:

Build         Last Digits of BDY number

12B              208874
12C              213656
12D              218542
01B              226339
01B              229291
01B              231468
01B              231654
01C              220831
01C              225292
01C              225431
01C              237549

From the 1st BDY number (12B build) through the 7th BDY number (last 01B build); if you plot the BDY numbers vs build date, you have a fairly straight line which would seem to indicate, that up to that point, the BDY numbers and build dates were following a logical and sequential progression.  

In the above list, the first 01C build is my car.  It and the next two 01C built cars have BDY numbers lower than the last 01B built car in the list.  From the trend of the 1st seven BDY numbers in the list, you would have expected my car, 220831 to have been an 01A build and the next two 01C cars (225292 and 225431) to have been late 01A or 01B built cars.  But all three were delayed, for some reason, to 01C builds.

I know there are a lot of reasons why a carís production could have been delayed including something as mundane as not having the correct color floor mats in stock at the time resulting in the building of the car being delayed until the floor mats were in stock (along with everything else required).  

However, what I have also wondered, is could my carís build have been postponed due to waiting on a few additional 327ís to make it to Norwood to finish out production of all 327 /  í69 Camaros ordered prior to 1 Jan 1969.  

So the question is this Ė is it conceivable  / possible that a 1969 Camaro could have been placed on order on Friday, 27 Dec 1968 optioned with a 327?  If that happened, the car would have obviously been built, after 1 Jan 1969.  I, like you, would like to know when the last Camaro with a 327 was actually built, but that information apparently has been lost to time.

The plant would know the quantity of 327's required to build up to 12/31 - that's the scheduler's job.
Data shows that the changeover really did occur right about the beginning of the year.
GM of Canada data shows the last 327 car be 9N571395.

There was no way to order a 327. It was just the base / default V8 engine.

The LM1/L65 changeover was a bigger deal - some LM1 orders would have been rejected or changed (and the dealer notified of the change) to L65 engines.

Thanks Kurt,

Good information.  This is the 1st time I've ever seen info on the last production 327 tied to a VIN.

From the 1969 End of the Month VIN Report table (CRG website), last VIN produced in Dec 1968 at Norwood was 9N569987 and the last VIN produced in Jan 69 at Norwood was 9N589720.  So in Jan 1969, Norwood produced 19733 Camaros.  From past info. provided by JohnZ, I recall the line rate was 912 cars / day.

VIN 9N571395 would have been the 1,408th unit produced at Norwood in Jan 69 and with a production line rate of 912 cars / day, that means that the last 327 went down the line at Norwood sometime during the 2nd production day of Jan 1969.

Good to know - I've always wondered -

Even better, here's the earliest known 307 car!  9N571561
http://www.ebay.com/itm/280808018806

BTW Richard, I wouldn't count on those end-of-month records to quite that level of accuracy.....

It also occurs to me that this changeover was a bit complicated by the fact there were 3 engine assemblies being discontinued and 4 being introduced. I'm pretty sure they'd order the various 327 engines and schedule them all to deplete about the same time. Not as complicated as some changeovers - it always amazed me how well the plant handled stuff like this. But sometimes things I thought would be easy......

Per the docs, Fathom Green (57) with Ivory/Black standard interior (727).

I know there are a lot of reasons why a carís production could have been delayed including something as mundane as not having the correct color floor mats in stock at the time resulting in the building of the car being delayed until the floor mats were in stock (along with everything else required).  

First of all, there were about 7,000 dealers ordering cars at that time. They were not equal in terms of influence with the Zone or the factory. A high volume dealer in a large metro area is in a position to demand and get better delivery lead time than a small dealer in a rural area.

For standard models parts availability is not much of an issue. Like many products cars are planned to a sales forecast. Chevy knew most Camaros [50%] will be ordered with the standard 8 cylinder engine. At both plants the production rate is 912 units per day; the constraint being body production or paint. So Chevy plans for about 450 standard 8 cylinder engines daily for each Camaro plant. All other standard components, same planning. Remember that production of everything is constrained by something.

What can become a problem is optional models/equipment. Chevy probably initially forecast 16,000 Z/28s for '69, twice '68 production, and planned accordingly. That means they needed 320 472 intakes, 4053 carbs, 480 distributors etc per week and tooled up for those numbers. When dealers started ordering 500 Z/28s per week, they could not meet that demand. November '68 Chevy sent a letter to dealers stating they would not accept Z/28 orders until further notice.

The BDY number was not assigned when the car was ordered; it was assigned when the order was confirmed back to the dealer. Norwood and Van Nuys were on the same system. All the confirmation meant was that the car could and would be built. At that point it was not scheduled. The BDY number has nothing to do with the scheduling of production.

At some point planners have to decide whose cars are getting built that week. Since there was very limited room to store them the ship to location had to be a major factor. Paint color may have been a factor; they did not have 18 paint booths. Cars also vary in labor content due to optional equipment; you can't schedule 75% of the days' cars to get vinyl tops. At the point an order was scheduled the dealer was sent a ďScheduled Price Sheet.Ē Very similar in appearance to a window sticker, it listed a scheduled shipping date.

So a Camaro built after cars ordered later was not necessarily delayed; it was simply scheduled that way.
