I have a 73 dart swinger that was passed down to me.it was half restored when i got it.i know the rear end was replaced but dont know what it is the car was being built with a 440.
Is a 8 3/4 rear end plenty strong enough for a nice small block and how do i tell what kind of gearing is in it.im new 2 this thanks.
That is plenty strong enough. To see what the gear ratio is, Jack the rear of the car up, mark the drive shaft, turn the rear wheel one time, as you rotate the rear wheel, count how many turns the driveshaft makes to one turn of the wheel. This will tell you very close to what gear ratio you have.
