The CHP Mileage Series Cam is designed for maximum fuel economy, while achieving the original stock performance, and works best in low-compression engines. When tuned to run 92-Octane fuel, the record is 22 MPG from a 1976, CHP in a full-size Sedan Deville. Great bottom-end torque at the expense of top-end performance as power peak is a slight bit earlier than the stock cam. Advances in cam technology has made this the perfect cam for those trying to get Honda-like MPG from a much more powerful Caddy Big-Block engine.
