Ok, you will need a 15/16 3/4" drive socket, a 6" extension and a either a long ratchet or breaker bar. A ratchet is more useful, as it allows for easier rotating. Probably should just purchase a 3/4" drive set that includes the larger size sockets and a couple extension lengths. You'll need, at least, a 6" extension, since the depth of the balancer and pulley assembly is deep. I say 15/16" as this is what's holding my pulley and balancer together in my 1965 289V.
Perhaps, someone else will chime in on a different size for your year.
