Chevrolet C15A APT (Airportable)

[Grant Bowker]

I was looking at the AEDB Design Record which gives 5.42 or 5.43 for the C8A...
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.

The New Zealand C8AX was reclassified as a 15-cwt truck after WW2 without any modifications. The CMP range was generally a bit over engineered for their assigned load classes.
