NHRA Approves Roush Mustangs For Straight-Line CompetitionSThe National Hot Rod Association has granted its approval to the 2008 Roush supercharged 4.6-liter V8 in the Stage 3TM and P-51ATM Mustangs. This marks the first time the NHRA has given the nod to an aftermarket powertrain; previous competition powertrains had to be as-delivered by the manufacturer. Depending on configuration and bodystyle, the Roush Mustangs will be classified between AA Stock and B Stock or SuperStock A and F. Look for the first Roush car coming from Haas, Carrothers & Wagner Racing; the team won three consecutive NHRA Division 3 championships from 2004-2006, and they're currently building a Roush Mustang with a Stage 3TM powertrain.
