Low gear set 904, pro’s and Con’s

No comparison between 2.45 and 2.74, but everything I heard or read about 2.74 low pointed towards benefits in heavier and lower torque applications. In my case it was in my 3,540+ lb 360 Dart with 4.86 gears and 30" tall tires. It helped it to a best of 1.47 60' times. NHRA class Stockers can get even better results in getting "extra", rule-mandated weight moving. On the flip side I've heard of lightweight big block Mopar vehicles with custom 2.20 low gear Torqueflite combos.
