calculating diff ratios
what is the most accurate way of calculating a diff ratio. would it be to turn one flange and see how many times the other flange turns or is there
another way

i take it its sierra the only real accurate way is to take the back off the diff and the ratio will be stamped on the crown wheel. dont go by the tags
these have been changed in the past by some less honest people.

How much difference does it actually make? I mean could you really tell the difference between a 3.18 and a 3.88 just by driving it if everything else
on the car was the same?

I think that's why people settle for a mid-range ratio, as with everything there are +'s and -'s the greater the top end speed the
slower it will pull away but lower top end great for drag racing at lights
