neither will if you don't build 'em to take 500 hp. the ford will take it, but think about this, the engine didn't come with 500 hp, you had to build it, same thing applies to the rearend, it wasn't made for 500 hp, you'll have to make it to take it........

If you're running 500hp or better, a Dana 60 is the best way to go. You'll get a lot more money out up front but it's the last time you'll have any trouble with your axles or center section.

Ford 9 inch set ups might be good for quick ratio changes, since the center section drops out, but they've got their inherent problems just like the GM eight-fives do.

Here is Currie's site. They build some real nice Dana 60 housings for a real heafty price. Good stuff though...

I'm beating my 9' with over 600 HP and I have yet to have any problems. All of the big three diff's have their strong points, but if you build any of them right the first time, they will serve you well. It took about $1700 to build mine myself. I started with a $50 housing, narrowed it and stuffed in the goodies. In a G-body, Currie sells a bolt in housing for about $700. Too rich fo my wallet. I just spent my money on ladder bars and coil-overs instead. Gotta just bite the bullet.
