Hi Spooky
The lowest ratio Austin made was 4.4 (9 to 40 teeth in Bill Williams Special building book), although I think these are really rare. 4.89 (9 to 44 teeth) is the most common ratio on most axles up to about 1932? Thereafter 5.25 was the norm. So at 3000 revs you’ll be struggling to get more than 47 mph.
Cheers
