Keith -

Specifications in the shop manual are also ambiguous.

However, the 1955 dealer album (p.48) shows only a 3.54:1 axle ratio for Packard with Ultramatic. which suggest that as standard.

With 3.54 listed in the parts book as the first ratio for 5580 (Gr. 12.001), and other listings are not in numeric order, by ration, the OPT designation could be a typo.

What ratio was actually used in the test car depends on what the criteria were for this test.

Meanwhile, I don't know what axle ratio was in my dad's old Exec, but he told me that he once ran it up to 110MPH on US 19, which was a two-lane blacktop highway (before they built I-79). He said the speed still was climbing, but can't say for sure what it topped out at. By that point, he wasn't about to take his eyes off the road again.
