For more than four decades, Ray Barton Racing Engines has built high-performance internal-combustion engines, with a particular connection to front-running Chrysler and COPO drag cars. The Robesonia shop handles 99% of its work in-house, from street and restoration engines to NHRA competition builds, and tests every engine it builds on its DTS dynamometer. RBRE also works with Chrysler, GM and other manufacturers on parts design and development, giving its engine work a direct link to the components it sells.
