Are you sure it's not a bearing knock? If you reduce the load on a cylinder (that has a bearing problem)the noise will go away.. Most bearing failure is on the 5 and 6 cylinders on the 300zx.. You could try removing the injector and coil connectors on the number 5 then 6 cylinders, one at a time.. If the noise goes away.. you know what it is..
Hope it's something less expensive
