Rough value on a '70 Cuda?

[Chris396]

I am trying to get a ’70 Cuda that I’ve known about for years. I’ve never seen the car but it was my cousin’s best friend’s. I do know that it has sat in a garage for nearly 20 years. The car is white with I think black interior. It’s a 340 car with an automatic and has a tunnel ram with two fours on it. He said the guy still has the 4 barrel intake and original hood along with the original wheels. So let’s say it’s got old paint and a mostly rust free body. What’s a car like this worth in estimate?
