One of my friends that knows i am a long time impala owner called me today asking if i need any impala parts because he has a wrecked one in his tow yard. So needless to say i go to check it out and from the outside it appears to be stock except for the polished rims. But when i look under the hood the motor looks a little different. There is no resonator for the airbox and the valvecovers have callaway scripted on them, as well as slotted and drilled rotors. And a super beefed up suspension.... Does anyone have any kind of info on this model?
