At Roush Yates Racing Engines we are now building custom engines for a wide range of racing applications. We have quite a bit of success in other racing series outside of Cup, Nationwide, Camping World Truck, ARCA and Grand AM. A Roush Yates Racing Engine means Quality, Power and Reliability. We take great pride in building the best Ford Racing Engines and we refuse to settle for anything less.
As this program grows we will have customer testimonials, race results and additional information on the engines. Please bookmark this page for weekly updates.
