Or, if you have a little extra cash laying around, buy a 2001 cobra and put on the following mods:
1) 4.10 gears;
2) Drag radials; and
3) ATI or Vortech blower (9#'s will be sufficient) maybe an injector & pump upgrade too
Let's not kid ourselves here, this will be one fast mother!
Good luck on your decision.
