1977 cougar info help...I know its not a dodge

I know, its not a dodge...lets see how long this post will last.

I got this car for free. My plans are to use it in Hit-to-pass racing so the car is going to get wrecked. The problem is that this car might be rare, and I don't know it. The options that it has are... BB motor, Auto, ford 9 inch rear, 2 dr, sun roof ( stock) electric windows. This car is in really good condition. I won't have any problem smashing this thing up. But I would rather save it, and sell it to someone if it is rare. I would Hate to see some rare mopars getting smashed up. If It was a dodge, I would know how to find outtheoptions it has, and if it is rare or worth something. but because it is a ford, i have no clue. I was told its a 400 BB, and its a 1977 cougar XR7.

Any help would be great.
