Just for discussion....the GV reduction is .78.....takes my 4:30s down to 3.35.
How much lower do you need in a hot rod?

More than that for my tastes. Heck, even 3.23 are pretty wrung out at 70 mph with a 28" tall rear tire. With 3.91's a .67 overdrive knocks the revs down nicely to an effective 2.62's ratio, and a lock-up converter adds a nice rpm drop too.
