We are buildind an Off Road EF Falcon with a hot Cleveland in it.
We have seen Toplaoders, Borg Warner Single rails and Tremeg gearboxes destroy them selves in resious off road applications.
We hate the thought of an AUTO
We are looking at a F100 4 speed. Its bloody heavy, we know bottom is usually useless in them. It goes 10 feet before you change a gear !
The one we have has a Borgwarner single rail input and output shaft and is the same length as a single rail.
Questions : Do they all have the same ratio's ?
What are their ratio's ?
Has any one ever broken one ?
Can anyone lift one ?
