I thought the T/A Fast Ratio made it 12.7:1?

Yes... the internal PS box ratios are actually all the same... the difference comes from the longer arms.

The factor screwed up on the E-bodies and didn't install the correct matching longer Idler arm (~70-C-Body.... aka Fast Ratio Idler)... to match the longer "FAST RATIO" Pitman Arm.

Regardless, add a smaller diameter steering wheel and you'll experience quicker steering yet!... and have the PS box rebuilt to tighter specs (IE: FF Stage 2 or preferably Stag-3).
