[Healeys] Transmission OD - 22% vs 28%

[WILLIAM B LAWRENCE]

I also run the 3.54/.28 set up in my BN1 and I'm very happy with it except 
for one quibble. The BN1 transmission coupled with the .28 overdrive ratio 
gives me two gear ratios (2 over and 3 under) that are nearly identical. The 
math says the .22 ratio would move the ratios apart slightly and possibly 
provide another usable gear ratio. I'm wondering if changing to a .22 would 
be worth the effort. Any opinions?
