No , the 1965 Ford Mustang offered the 200 cubic inch inline six cylinder and three versions of the ( 289 V8 engine ) from the factory

The 1964½ Ford Mustang did not have a 289, it had the 260 (which was rated at 164 hp). If your car has a 289 it is either a 1965 or does not have the original engine. A good way to tell a 1964½ from a 1965 is whether it has a metal dashboard or a padded dash.
