Nuetral safety switch ?

Just tried to start newly rebuilt 360 with rebuilt 727. Will the nuetral safety switch not allow the car to start, by not activating the starter relay? I can jump across relay and spin motor. Also I have put trans. fluid in but I am still able to roll the car around with the colum shift in park.will that change once the convertor fills up?Will that also correct the nuetral safety switch issue?
How do you check the safety switch? Can I bypass it for now?
