i am looking for the pdf of where "Blumbly" got the extract for the corvertie [sic] from it should be in a series 70 green book pdf
Hello dmitr

Alright. Happy to help out but I want to point out the complexity in all this.
You have asked for a lot here.

The Green Books are not set out covering models sequentially.
The manuals are divided into sections and caution should be taken
in reading them. They require interpretation.

Here, I cover the 2-stroke Corvettes from 1968 - 1972.

The gallery images are the key.
I have used yellow highlights for this.
I will attach pdfs of detail in the next post.

Hope this helps.
