[Fot] T5 conversion

[Larry Young]

It should be mentioned that some groups don't allow a 5-speed (e.g. 
CVAR).  The jump from 2nd to 3rd is one reason I switched from a 3.7 
close ratio to a 4.55 close ratio with overdrive.  With the later setup 
3rd replaces 2nd, 4th replace 3rd and 4th-OD replaces 4th. The jumps in 
the top three gears are about 20 percent.  It seems that with most of 
the tracks I ran on, I needed 2 gears for most of the track with perhaps 
a higher gear needed on the longest straight or a lower gear in the 
tightest corner.  I remember one time when I lost a throw out bearing at 
Hallett.  I lost only about a second using just 3rd and 3rd OD. I know 
an overdrive is "old school", but you get some good ratios and the 
satisfaction of knowing you a truly vintage. I seldom had trouble with mine.
