In the build of Buzzing Half Dozen, we'll clear the smoke and relate the story of how these lightweight aluminum wonders came to be. Then we'll hammer one together that makes better than one horsepower per cubic inch on 91-octane pump gas. Finally we'll stick it in a 3,000-pound A-Body and show you how easy it is to run low fourteens at over 90 mph with any Slant Six, cast iron, or aluminum.
