[Healeys] Rear axle ratios

[Harold Manifold]

Jonathan,

I wondered the same thing myself and created this table when restoring my
car.

Overdrive Ratio        0.82        0.78        0.82        0.78
0.82
0.78
Rear Axle Ratio        4.10        4.10        3.91        3.91
3.55
3.55
Final Ratio        3.37        3.19        3.21        3.04        2.91
2.76
Engine RPM @ 60 MPH      2,624      2,484      2,502      2,368      2,269
2,148
Just to further muddy the water there are two OD ratios available in
addition to the three rear axle ratios. I have the 0.78 / 3.55 combination
and my Healey happily cruises at 60 in OD.
