You do know that adding a 4bbl to an otherwise stock 273 2bbl combo is almost a complete waste of time .... right?
You'll have far greater results with adding more rear gear. Far greater.
Have to disagree with you AJ....did just that on my Dart 273, and now it runs WWWAAAYYY better than with the 2bbl. Yes, it's no race engine, but for the street cruising, it's much nicer.
