1965 small block casting numbers

[Dan A.]

I just took a look in the new 6th edition 1965 technical information & judging manual to see what it has to say about 870 and 180 casting number blocks during the '65 model year. Unless I am looking right at it and not seeing it I see no mention of the 180 block.

Is the Tonawanda 3858180 block no longer recognised as being used in limited numbers in 1965 model year Corvettes?

I believe there is a typo. In the folowing sentence they meant to type 3858180 instead of 3782870.

"The Tonawanda cast # 3782870 block was typically not used during the 1965 Corvette production"

That would seem to be a very significant mistake.
