The only spec I have for a 1970T is 35 degrees BTDC at 6000 RPM with the vacuum line disconnected.

FWIW,.....35 degrees is too much for today fuels. We set them at 32 degrees to prevent detonation, especially in warm weather.

I thought the T had cab's and 8.6 to one compression. I would think that something like Rec 90 (non alcohol) would run fine. Setting it at 32 wouldn't hurt though.
