Low gear set 904, pro’s and Con’s

I only know one guy that used the 904 lo set in his stock lo compression 360 duster and he liked it
with 2.94 gears. I'm not a quarter miler and I think that may calculate to about 3.30 through 1st
and 2nd gears?

A 2.94 rear axle ratio and a 275 low gear is 8.09 overall in low gear.
