Have you ever wondered HOW the NASCAR race engines of today evolved from the street driven versions? Inside the RFK Racing (Formerly Roush Racing) Museum they have a C3 Engine from the 1990s, a D3 engine from the early 2000s, and a current FR9 engine used in NASCAR racing today. We met up with Jeff Clark, the EVP of Roush-Yates Engines, to get the full story on this engine timeline. Jeff was hired by Robert Yates himself to be the Jackman on the 28 car of Davey Allison and witnessed much of this development firsthand. The engines shown here have powered the wins and championships of legends such as Alan Kulwicki, Mark Martin, Davey Allison Dale Jarrett, Matt Kenseth, Kurt Busch, and Joey Logano.
