Congrats, great car, looking forward for more pics.
VERY NICE !!! GOOD GOING need to ask a ??? from what i read and from other people they say the engine is made 1 to 3 months before car date on vin tag
My 70 has a 3/26 engine and a 4A cowl tag date. The build date on the build sheet is 4/06 so the car was built about 11 days after the engine was assembled. Other cars will be different depending on how far ahead or behind the engine plants were compared to the car assembly plant.
And, the engine was assembled at Tonawanda, NY so it traveled across the US to Van Nuys, CA during those 11 days.
Is your car an SS or Z? I think 100% of the Z engines were Flint assembled. "V" in the engine code is for Flint. I read I think either here or on the Supercar or Camaros.org forum that Flint was the only location that had the tooling to unshroud the large 2.02 valves in the heads.
Anyway, for another data point my engine block has a 3/16 casting date and a engine stamp of 406 and a car TT date of 04B and its a Norwood car. I think a month is about the limit I've seen for the engine cast-TT car build window.
My car is an SS, but I don't believe that made much difference. Chevy was geared up at all plants to produce cars fast and continuous. Once in a while they probably got a bit ahead with the engine production, and once in a while they might have been running a bit behind, but to make money, they needed engines ready at the car assembly plant to keep things rolling every day.
Very nice conclusion. Good 1.
