So if we have a bunch of cars with VIN numbers assigned after Jan 1 1969 but still with 327 engines, do the Trim Tags on any of them say 01A not 12D? Now THAT is the real question.

I WAS under the impression that this all was related to the fact that the 327 engine did not meet pollution requirements that went into effect Jan 1 1969, but that the 307 engine did. Of course the 307 also lost 10 rated hp 200 vs 210 and generally is not seen as the greatest small block V8 Chevrolet ever built, whereas the 327 is something different from that entirely!

Part of this involves the deal GM must struck with the EPA regarding the dates over which the new standards applied barring the 327 as installed in 1968 and how the transition was carried out so all cars could be sold.

I could believe that the car was mostly complete with a 327 engine already installed and the 12D trim tag in place by Dec 31, 1968, but that the car did not actually roll out of the plant until Jan 2nd 1969. That would be consistent with the idea that no Camaro had a 327 installed after the Dec 31, but not everything that had a 327 installed had rolled off the assembly line to be shipped to a dealer on Dec 31 or earlier.

General Discussion / 307/327 build dates

« on: April 05, 2023, 07:23:47 PM »

I ordered my 1969 Camaro from the factory the last week in November 1968

I still have it.  The Trim Tag says 12D and the sequence number on the Trim Tag says NOR217772 
I have long interpreted the Trim Tag build day as the 4th week in December, 1968 probably in the days between Christmas 1968 and New Years Day

The car arrived in the first week in February of 1969 and I took possession.

The VIN on the car is 9N570099  which is a later number than some guys claim in the maximum number a Camaro built in 1968 can have, but the Trim Tag says 12D

Between when I ordered the car and when it arrived, I got a copy of the new sales brochure which claimed the standard engine was the 307 not the 327. But I also have the earlier brochure listing the 327 as the standard engine.

The first thing I did when I saw the car is to see whether the fender numbers said 327 or 307. THey said 327

I always thought my Camaro was one of the last to roll off the Norwood line with the 327.  The original 327 is still in the car. 

But some of what I have just said does not jive with the earlier 327/307 discussion about when exactly GM swapped. My understanding that all cars with the standard V8 built Jan 1, 1969 and later had the 307, but if earlier, the 327

The 327 V8 is a nice engine especially when paired with the 3-speed Turbohydramatic :-)
