By now, it’s no secret that millions of fans hope to see the recently updated Ford Mustang get a much-needed power plant upgrade in the near future.  Well, Mustang fans, we’ve got some interesting buzz for you.  Today, Ford of Australia’s Russell Christophers hinted that a new 5.0 liter V8 codenamed “Coyote” is currently in R&D in the US of A.  That’s right, the SEMA rumors seem to be heating up closer to the boiling point of truth, folks.  If this 5-oh comes to fruition, sources say the numbers tach in at 400hp and 400 lb-ft of torque from the DOHC motor.  So now, it’s not a question of “if” the Coyote will come to pass; it’s a question of “when”.  Many say 2011 or 2012.  Conjecture is welcome, as no one can say for certain, given the volatility the market (and aftermarket, for the matter) is experiencing.  Until we hear more, stay tuned…
