Thats quite a story on the '52 Ply. going 65 mph in low. So I did the math: 5280 divided by 7 ft.(size of tires) times 4.11 (rear ratio)= 3100 eng rpm @ 60 mph so @ 65 mph the eng. rpm is 3358, with a 1st gear of 3.54 @ 65 mph the eng. would be turning 11,887 rpm.....(WOW) Now if Hudson could get that tractor turning that rpm he could really smoke those tires.
