carb. crazzzzyness!!!!!!!!!

A spreadbore (ThermoQuad or Quadrajet) is best for driveability and mileage, but good used ones are rare. I vaguely recall reading of new Quadrajets. TBI would be even better, but more complicated. With either carb or TBI, you need an O2 sensor or you are "flying blind". Best is a wideband kit and prices have greatly dropped.
