How much is it worth?

Thanks in advance for any help. My dad recently passed away and I am trying to settle his estate. He had a 66 Barracuda that is all original with the exception of a new paint job he had done a few years back. Nothing else has been done to it to my knowledge. It has an original slant 6 motor. I was hoping you experts could give me an idea what its value is. As per his estate I have to sell everything and divide it amongst my siblings and myself. Thanks in advance for your input.
