Good info. I see the Air over Hydraulic option for the C-60. Interesting that the 4-53 Detroit is no longer available in '66. Probably because of the new 366 Big Block option. Of course, I say that was a mistake, lol. The should have kept the Detroit, but strangely it was only available in the C-50.
