She comes with 455 CI big block with a turbo 400 transmission and a 12 bolt rear end. This is a factory AC car and it does work, along with the original am/fm radio which still works great. She was restored and had the frame media blasted then painted, also she has many layers of base coat and clear coat which gives her a mirror like finish and there are no waves at all it's laser straight. She does also have tilt wheel steering. The car floats like your on the cloud when you are driving it and the 3" flow masters make her sound awesome.
