Another way of looking at it...

Say you buy a 2015 "Genuine Shelby" or "Kirkham" roller, and you take it to Greasy Joe's Garage and pay him to install the motor and tranny. Do you call it a "Greasy Joe's Cobra"?
No, certainly not, you call it a Shelby or Kirkham because that's who "Manufactured" the car (Or maybe not in the case of Shelby, but that's another story).

So on that same reasoning you would naturally call it an AC would you not???

I think like other branded tuners you should use both names. AMG Mercedes etc.
