So they did produce Z28 cars withe 08C build dates on cowl tags, they just did not for 08B??  Thnks maybe my motor is not the original one, but it sure corrct inside and out for a 69 DZ motor.  Maybe a previuos owner purchased an entire complete motor for the car???

Yes, that is correct. Th block is a 3970010 casting number,  cast date is May 25th. The heads are casting number 3921786, correct for the DZ 1969 motor and are casting date May26th, so the heads sound right for the engine build.  also while the engine was rebuilt and balanced the internals are all correct parts and specs as well.  I have all specs on the report for the engine work.  I figured the trans and rear axle are not original, but the motor??  seams like it is.  car has original smog equipment, seven blade fan with clutch, deep gruve pulleys, intake is winters 3932472. The car recieved a very high end and very correct restoration a few years ago.  The  car is an X33 car with endura front bumper and cowl hood,  bllack top, black stripes,  rosewood wheel. The original owner verified that he ordered the car this way as well.   I am just trying to get to know everything about the car and there seems to be alot a views and variations of chevy builds.  If the motor was built after the cars build or 5 to 6 months prior to the car build it would then be a  be a no brainer!!!!!!!!!!!

Decoding/Numbers / 1969 Z28 engine build dates and cars build date spread time??

« on: August 27, 2008, 12:05:41 AM »

My engines build date is May 29th, the blocks casting date is May 25th, the heads are cast May 26th. The stamp on the front machine pad looks legit V0529 DZ and all things fit the puzzle for the motor,  but my cars build date on the cowl tag is 08C, August 3rd week correct. The question is could it be possible that 60 to 80 day spread between engine build and cars build???  I have spoken to all previous owners and all state that the motor is the original one and forget about trying to read the numbers on that rough pad by the oil filter while the engine is still in the car! I have read enough questions and threads on that topic in this CRG forums.   So can it be?? Is 60 days too long?? How long did it take to get a finished motor from Flint to get to Norwood.  I am very sure my car is a real Z28 hugger orange on hugger orange houndstooth, but is the engine the original DZ motor?? Thanks for the help.       PS I have learned so much from this Forum it is sick and I appreciate all the information.

My cowl tag says 08C for the date not 08B sorry. What do you mean there is no 08B date??? I have read that engine builds can be 60 to 90 days before cars builds but is not the norm, usually it is 1 to 6 weeks before the cars build Right?

I can not seam to find any numbers on the rough pad near the oil filter where it should be my Z28 is a norwood car with a build of 2nd week in August 1969. My DZ motor build is May 29th Casting date for block is May 25th, heads casting dates are May 26th. All previous owners have stated the motor is original espec. the original owner. I have talked to them all. The V0529 DZ cade looks original with no partial vin stamped by it , but there are 5 large numbers 01877 that are stamped off to the left. I was told they are  the engine's  first rebuild date  done at the machine shop. Jan 8th 1977??? These numbers are larger and not even like the factory V0529 DZ stampings.   I know the oil filter location is hard to see, maybe factory did not stamp vin on this one?? Any tricks to seeing them???
