OK, from memory, this is what the Chevy bulletin said:

The distance the center of the cable stud on the carb throttle lever is supposed to be from the center of the throttle shaft is 1.160 inch.

The full travel of the cable, idle to WOT, should be 78 degrees of arc.

When the carb is opened half way, the cable mount should be straight up and down in line with the throttle shaft. This would give 39 degrees of mount arc back to idle, and 39 degrees of mount arc to full throttle.

I used to have the bulletin in my possession, but, no longer. Ask your local Chevy dealer's service adviser, they should have this info they can copy for you.
