The car was built as a special project car , the exact date that this was done Im not sure. The paper work I have on the car indicates 2002 but I think that was when the car was sold to the previous owner. The car was owned by a Roush employee who sold the car to Craig barker who was the power train manager at Roush at the time. They yanked out the 302 put in the 351R along w/ a lot of prototype parts that went onto the R. The part I have not found out yet if this was done before the R's release or if it was prototype parts they had left laying around after the R came out. I contacted Craig Barker at one time but hes not much for words. Hes not to happy the car was modded at all from his original mods that he did. This was mostly directed at Jimmy the previous owner. Only thing Jimmy did was put on better heads, cam and a supercharger at that time. Anyway the Hood, Mass air, Valve covers, ECU were all prototype units. Barker put in a custom program into the ECU which is prob why it has not been to mod friendly but that will be fixed w/ the dyno tune and chip on May 2.
