I need some schooling. Building a nostalgia gasser Falcon, and it came with a 9" out of who knows what. I've already ground off all of the useless brackets, and I'm getting ready to get the housing mounted into the car. Since it will be drag only, what are the pros and cons of using a 28 spline versus 31 or 35? Are they bigger? If you bought 28 spline axles from, say Moser, or Currie, are they strong enough? I'm shooting for between 400 to 450 H.P. What about the center section....would I be better off running a spool? Or better of running something else, like a locker, or limited slip? What gear? How would I go about figuring out what I would need? (4:11? or ?) I need some good drag racers advice.....this car will not see the street at all. Thanks!
