Ricky Rudd was the only driver using the next-generation Roush-Yates engine in the 600, and the results were mixed. The motor provided reliability and more power, but his #21 Air Force Ford couldn’t match the performance. “The motor was good, but you’ve got to have a chassis that complements the motor,” Rudd said. “We were bad in the corner, so we couldn’t take advantage. This motor liked to go, but we were losing about 300 rpm more in the corner than we should have been.”(Richmond Times Dispatch)(6-1-2004)
