I live 2 miles away from WOR 710's transmitter site in NJ. I am receiving
them loudly on thier 5th harmonic on 3.550 MHz. My question is: by how
much does an am broadcaster have to surpress thier hormonics?

Are you sure that the harmonic is not being produced in your receiver?
Some sort of non-amplifying preselector will confirm.
