Maximum competition, comp/modified drag racing, circle track. Over 7,000 RPM, high compression. By reducing the valve angle, reshaping the raised intake ports, and optimizing the combustion chambers, we produced a significant increase in both airflow and combustion efficiency – and that means more power. Dart delivers the features that put you ahead of the competition. We’ve refined the 18° design to give our customers more versatility, more performance, more reliability, and higher quality.
