Vizard ported a stock intake with a die grinder, just rounded off the corners, and narrowed a few walls. He claimed that his home ported Chevy intake was superior to ALL aftermarket intakes for a stock 350 motor. Of course, 30 lbs off the front end is nothing to laugh at either with an AL intake. If yoiu need a carb, get the stocker. Youll probably not feel any difference.
