In case anyone is wondering, this is the infamous "Christine" as we called it that had spent quite a bit of time at TDR. I don't know the specs either but Michelle is probably correct with her estimate. I believe the motor was rebuilt with stronger internals and possibly port work. Gary at TDR would know more. It was also painted by Rogue and appeared at MWII.
This is a heck of a car and a fair price.
