Looking for some help to determine what this car is worth.

Original 361 has been removed and a big block 1964 413 cubic inch to be put in its place
Push button automatic transmission I have the original and the one that came behind the 413
Floors pan is rusted out needs front pans. I do have a complete floor pan that comes with it along with a new trunk lid.
Interior is there but needs to be redone
This car came with factory air power brakes and power steering
