Hi I have a 91 GT 5.0 and it's a aod w/ TCI street fighter tranny I have a brazed converter, 190lph fuel pump, fuel pressure reg, pulleys, american thunder cat-back, mac headers, then a bunch of suspension parts anyways should I go with 3:73's or 4:10's I'm a senior in high school and hit up the track whenever I get the chance but not every weekend.
