72 340 value?

we have a 72 340 that my boss wants me to sale. it has been rebuilt and has 0 ring ridge, turns over free. has the std 4 valve relief pistons @.030 over, cast crank, hyd lifters, cam looks good, has windage tray.
it does not have heads or front dress items, or even timing gears.
I am not sure of cast crank 340 value so any opinions are welcome, it was already dark so i did not get any pix but it aint much to look at anyways.
