[Healeys] Engines and gear boxes

[Rich C]

Bernard,

You can interchange the side shift gearboxes betwen the earlier 100/Six and 
the 3000 roadster but keep in mind that the gear ratios for 2nd gear are 
very diferent. On the 100/Six, 2nd gear is much taller, allowing higher 
speeds in that gear, and an almost even ratio between 1st and 3rd.
In the 3000 box, 2nd gear is a lower ratio and closer to 1st.; the reasoning 
being that instead of trying to mesh an unsynchronized 1st gear, 2nd could 
easily be used from a dead stop, utilizing the extra torque of the new 2912 
cc engine over the earlier 2639cc engine.
