you sir now require a rebuild. 70 is low period and unless this is from a freshly rebuilt motor you are in need of one soon.

Make sure you tested compression holding the throttle all the way open. Also best done on a warm engine.

Well if the car hasnt started and youve got equal compression all around the next steps would be to check for spark and fuel since it will obviously crank over for teh test.
