408 crank?
"Ya know you hit the nail on the head. It typically takes 500 hp to put a 3000 Duster or Dart in the 12's. That's fast no matter where you are. If you can have 525-550 reliable hp there's no a lot on the street you can't whip. I'm not promoting street racing of any kind."
You're kidding, right?
You stud question was answered in the main studs thread... Me, I modify the stud (cut it), the 12pt nut (grind it), and sometimes the pump(grind it) rather than vary the faastener type. Others use bolts.
