Need Blackbird info....
I am trying to get the specs on any aftermarket parts the car has installed, but I doubt 380 rwhp without at least headers, cat-back(do these cars come with the GMMG exhaust?), and a cam.
Please let me know so I can tell my cousin what he is really getting into.
THANKS!
Does anyone else have info on these vehicles?
A hand full of the birds came back for the 435 HP Phase Two package.Thats a heads cam header package and they average 395@ the wheels through cats and what not.If it does have a phase two package the throttle body and heads will be stamped as such and definitely have headers.
Again average 380 HP Black Bird makes 340 HP/350TQ @ the tires.
