[Healeys] Speed Calibration

[J. Scott Morris]

   Hi Bob;

   Here is an Excel spread sheet I developed many years ago that
   calculates MPH & RPM given various rear-end ratios and overdrive
   reductions.  The various inputs are identified in !blue" and a graph
   is provided which illustrates the MPH at given RPM.  The spread sheet
   is based on two sources:

   1.       "Laycock Overdrive - Section 1: Working Principles,
   Maintenance and Fault Finding"

   2.       "Laycock Overdrive ...as fitted to the AUSTIN-HEALEY 100"  a
   brochure provided when each car was purchased

   If you have any questions, do drop me a note.
