2:91 or 3:55?

a friend installed 2.94's in his stock lo compression 74 360 duster along with a 904 modified with the later transmission lo first and second gears.
said it had tremendous low end and cruised smooth on the highway with no noise or high rev harmonics.
lol... exact same drive train as my '76 Duster, except my tranny is stock. Low end torque is not a problem, and it cruises so nice at 60 mph going to the dragway.
