F*rd 8.8 is another alternative. Common, cheap, strong (in some ways better than a 9") and can bolt in with a few small modifications. They aren't the last word in rears at all, just a viable option.
Good points. I don't rag my stuff, just want a good cool ride at a reasonable cost. The more input the better as this is out of my line of what little expertise that I have. I get that you cannot have it ALL.
A fully-built Currie 9-inch for G-Bodies is about $4,500. Yes, jaw-dropping money, but the list of hardware is drool-worthy.
It is a lot of money and it puts my 357HP crate motor delayed even longer. I want to do it right the first time as I am too broke to do again. I like "Cool" on a ride so it is a tough decision. Like I say I don't rag my stuff....but...there are occasions when...I lapse into....when a true friend is sitting next to you in jail saying "Damn that was fun"How much power do you have? If your not beating on it the 7.5 will stand up. Couple thousand is a lot of money.
If that's the money you're droppin', I'd lean toward the Strange Dana 60. It's as strong, has bolt in axles, is lighter, and more efficient than a 9". Frods rob power, and unless you're going big block or crazy boost, you will be sucking up a drivetrain loss.
