Handy chart here.....

http://www.1962to1965mopar.ornocar.org/ ... chart.html

gives Gear Ratio/RPM by tyre diameter

If anyone can get the chart posted here in full without having to use the link (copy & paste just comes out with a jumble of numbers rather than an easy to read table), be my guest.

They are not as good as mine. I included a speedo gear calculator and tyre diameter calculator as well.

Thanks Dave, yes, very good

There was a speedo gear calculator on that 62-65 site as well, but the tyre o/d's didnt match those listed on the gear ratio/rpm chart

so I thought it prob wouldnt be very reliable

I'll go with yours
