 Also, in 2007 and 2008, Roush produced 100 per year of the all-black Blackjack Mustang, and the top shelf P-51A and P-51B mustangs.These cars featured a Vapor Silver / green paint scheme, accented with Satin Silver hood scoop, chin spoiler and rear wing (in a tribute to the P-51 Mustang fighter plane of WW-II).The engine internals were upgraded to a forged rotating assembly, allowing a larger Eaton TVS R2300 Roots supercharger.
