Should I expend in a 742 third member or in a Dana 60 whole axle?

the smaller stem is not what USUALLY breaks, the ring gear teeth is what gives up. gear deflection !!

My doubt remains. If I look for a manufacturer which build a ring and pinion with a special forged steel (more resistant material), for example. Would my 741 support my 440 4-spd?

go ahead & build the 83/4 it will be just fine,

It is not just a matter of the size of the tire but also the tread compound.
If you plan to beat on the car, why not default to what the factory did? If you leave the line easy and just hammer on it from a roll, you will probably be fine with the 8 3/4" setup.

Yup, and then whats the point of a 4 speed if you are going to baby it?
