    .. it seems that your car was built in august of 1970 , not 71 . gm had a pretty early startup in 71 with some cars in the registry with low vins and 08 build dates ..there is a camaro in the registry with a vin of 00003 and a 08 B start date . the latest 71 in the registry is a 06 b and a 97,000 vin . i want to bet your vin is very low ..http://camaro2ndgenerationregistry.net/1971-registry/

    So if my cowl build date is 70, not 71, does that mean it would have had a `70 cast block not a 71?
    It`s a Los Angeles car not Norwood btw..
    Thanks

    I agree with this. - If the original block is long gone it's not going to matter what date you put in there, ( unless you are planning to restamp the block, which is highly frowned upon in the hobby ).

    A much better option would be to find a mid-to-late 1971 CE stamped block, which is the Counter Exchange block and is the replacement that would have been inserted in your car if the original block failed while under warranty. - Most CE blocks used the original heads, intakes, and everything else that was usable when the block gave up.

    Just check your VIN, then you'll know if it's a very early or late built 71. If it's a early built 71 then you'll need a block made/built in 1970. Anywhere from 1-4 weeks is typical but more than 4 weeks was also common. As mentioned, a CE block is also another option.

    that was my next question ... LA or Norwood ? but i see its an LA car . it seems by the data base that very few cars were built at LA and the majority were built in early to mid 71 . it also seems that gm built a few thousand cars in late 70 ( 71 cars though ) and stopped production .. this was common as estimated sales governed scheduled production . bit like i said your vin will tell , but it seems that NO 71 cars were made after june .

    Had a buddy run to my storage..
    vin is 124871L501830.
    Cowl tag is 08E and is stamped `71 in two different places on the cowl tag.

    That VIN should be one of the last 1971 Camaros built at Van Nuys in August of 1970. On that early a car all casting numbers would be 1970 on engine components.

    we would knock out about 1000 cars a day at tarrytown ( 480 minutes in 8 hours X 2 shifts and usually we ran over time in increments of 6 minutes ) . plants ran 2 shifts as each plant needed some time for stock relocation and maintenance . LA ran 2 lines at that point and was running about half speed or 30 cars per hour per line with 2 lines though . so 1800 camaros ( not counting the other cars that were run ) in 2 or 3 weeks is right on schedule .
