Everything else is good, but please rethink this statement.

Torque is what snaps things. To the rearend, it doesn't care if you have 250hp or 500hp. Torque is what will kill it. A LS1 or 302 will make a lot more torque that a T2 motor. And the way you drive it will make a lot of difference also. Dragstrip starts will kill it a lot faster than daily driving. You could have 1000hp/1000Tq and not snap the stock drivetrain IF you drove it like a grandma.
