earliest 67 3916323 block?

[Steve Shauger]

I was going from memory and just checked my records and all three blocks were cast F (June) 8th of 1967. I believe in Colvin's later addition of by the #'s he modified that statement to say that some late 67 cars in fact came with the 323 block. BTW two cars were built 7C and one 7B.
