Since 1979, Jones Cam Designs has been the cam of choice for top engine builders in virtually every form of racing. Our unique “Parametric Profile” cam designs are part of our proprietary “Total Engine Design Equation” (The Brain Child of Indy-Winning Engine Designer Dick Jones). As a result of 30 years of empirical data gathered from actual dyne testing and 50 years of research and development, Mr.Jones discovered a mathematical relationship between all engine parameters.
