Hello Charlie; Here is an excel spread sheet that will calculate your speed
given different transmission final ratios, tire diameters, rear axle gear
ratios, and engine rpm. At the moment the inputs are for my MkII Tricarb.
Just change the red input items to suit your car.

The Austin-Healey overdrive ratios are 28% and 22% which are the first
two numbers in the serial number shown on the plate on the overdrive
unit. How does that translate into figuring what the ratio coming out
of the transmission is? For example, 4th gear is 1.00 to 1.00. An
overdrive ratio would be 1.00 to (a number less than 1.00). Obviously
it is not 1.00 to 0.28 or 0.22. Would it be 1.00 to (1-0.28) or 1.00 to
0.72?
Thanks.
Charlie
