Hey John first welcome to the site and all the members have been very helpfull with my car.
First your car was built alittle before mine and is still an O8C date on the trim tag interesting. You would think that would mean 3rd week right, well No they skipped the 08B code so 08B cars do not exist. I calulated that my car was finished some time between the 7th an dthe 11th of August using the numbers found on this site and in Jerry's book. My car is 672077 and yours is a few hundred before mine and both are 08C cowl tag dates. They produced aprox 300 cars per day.
As far as the dates on variouss parts on your car being earlier than the norm, mine are too. This can be because the August and on, extended camaro production, was begun without much notice at all do to the problems with the much anticipated 1970 model witch is know as a 1970 1/2. Many parts had to be located very quickly and from various other places and things were very lax at times so good to see that many parets on your Z28 have a wider date span than the norm.
My engine block is a May 26th casting date/ Heads are May 27th casting date/ Engine build is may29th Flint. Front Pad stampings are original and My cars vin is stamped on the rough surfaced pad by the oil filter. i have spoken will all previous owner evn th eoriginal owner annd all stated the engine to be original.
What is the dates on your motor?
the normal span should be 1 to 4 weeks, but mine is more than twice that and it has brought up some questions. I believe our cars are special as they are cars that might not have ever been. My hood is the original cowl hood with either a week 20 or week 28 stamping on the drivers side lower rear corner.
