124379N637386 COPO Camaro 427 Block

[L78 Fred]

-Possibly a early May - I have a 04C L78 Camaro with a vin 2,094 units prior with a final assembly date of April 28th at 912 day production that could have pushed this car from a 04C to 05 car
More data points- even though a number of the later 512 blocks have early casting dates- this one is very close-
I have 272 L78 blocks D 15 9 2,000 before my vin and D17 9 2200 after my vin which is pretty close to the D21 9 which is 2,094 from mine or 2 1/2 days -if my thinking is correct- for these non standard cars
