It depends on how much torque you're putting through them. Some of these guys are running 302's and 351's with not much horsepower. Running through an open diff on street tires, it's hard to tear stuff up.

If I'm putting out any power at all, I'd feel a lot more comfortable with a nicely built 8.8" Ford or a 9" Ford if running a solid axle.
