Just when I was sure I had a real L78 someone told me that you couldn't get 3.73 rear end stock from the factory with the Turbo 400 transmission. Is this true?

For 1969 the L78 engine came standard with 3.55 ratio, regardless of transmission. Here were the options, also regardless of transmission:

Economy - 3.31.
Performance - 3.73.
Special Order - 4.10.

Dealer Installed - 4.56 and 4.88.

Hope this helps.
