Which speedometer gear do I need for my 727 tranny, 3:23 rear end, 215/75-14 tires?
 
I think close to 26 tooth would work.
 
And a chart from the internet says 32 tooth gear.

I got a bum calculator it seems....another one shows 32 tooth...just hang fire a few minutes.

Your tires are 26.7" diameter - so a 32 tooth looks closest.
