ran the Duster today.....

Yes and a highway car as well no OD needed. Nothing like hyundias passing u while buzzing like a chain saw at 60.
U have a good simple receipt for torque that's what can pull a 2.45 gear. Learned that lesson in the 70s w a 65 Olds
98 with a 425ci and highway gears that torque monster did not lose a lot of races ask my buddy w 71 LT1 vette w gears.
