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

I am running a 7 1/4 behind my 360 727 with no problems. The motor is your standard 360 build. good cam, rpm intake, 650 cfm, headers, and ignition. I am HARD on that rear end and it has still not failed me. I have a 8 1/4 in my garage so I have really been beating it recently and it still will not break. By beating it I mean every time I drive it I am power braking it and kicking it sideways around every left hand turn I come up to. I think you will be fine as long as you keep it straight and dont hook up. As long as the tires are spinning its not going to be THAT tough on the rear.
