Six Cylinders Against the World: How Buddy Ingersoll's Turbo Buick Shocked NHRA Pro Stock

In the mid-1980s, when Pro Stock was dominated by big-block V8 Chevrolets and Mopars, Buddy Ingersoll shocked NHRA with a turbocharged Buick V6 that could run with—and sometimes beat—the naturally aspirated eight-cylinder monsters. His compact 231-cubic-inch turbocharged engine proved that forced induction and advanced engineering could match raw displacement. Ingersoll's Buick challenged the Pro Stock establishment, forced NHRA to reconsider its rules, and demonstrated that American ingenuity could turn a "grocery-getter" engine into a championship contender against all odds.
