What can a 7 1/4 rear take???

Wow a 440 on a 7 1/4? That must have been hard not to blow that rear end out for that year. That gives me more hope for my little 7.25. Like I said, I am not going to race or hot rod the car. I just want a nice driver that will last the test of time. Maybe down the road ill look for an 8.75, but for now I'd like to stay with what I have.

Mrgtx after you had the 7.25 rebuilt/fixed how does the car run? To clarify, does the rear end work as it did before, or do you think it can take more abuse because of being freshly built?
