[Healeys] non-overdrive sidewinder boxes

[allen c miller jr]

I've located a non-overdrive gearbox and am preparing both 4.11 and 3.90 rear
enda for  light racing events with the BN2/m. will be working with low tune M
spec engine
and keeping under factory redline this season, but anticipate higher
performance revs in subsequent seasons.

can anyone give guidance on gear sets available, and which ones  would best
suit needs. typical event would be Lime Rock.

thanks
