However, when I look at the C8A-04 parts list earlier C8A are listed as 6-37 ratio (teeth on pinion and ring gears = 6.17 ratio) and later as 7-38 ratio (matches AEDB record).

Yes from memory the C8AX has the two ratios, one is faster . Some years ago I was following Len Schutt's C8AX down the Hume freeway coming back from Corowa, Len was getting up to a good speed, around 90kph , this with the original 216 engine fitted. I was impressed at how fast the C8AX was moving, my old XF Falcon was struggling to keep up..well may be not struggling but we were not dawdling along.
