Did you build the motor? A Chevy? I'm not sure exactly what your problem is.... I assume you're trying to be sure the cam timing is correct... get a friend to help with this part, it's easier... put your finger (or your friends) over hole #1 and using a long wrench on the crank bolt* bring the piston to the top of its bore on the compression stroke.... the cylinder pressure will push your finger out of the hole. The timing pointer should be showing '0' or TDC, depending on your engine design. Also at this time, with the valve cover off, both intake and exhaust rockers on #1 cylinder will be free of pressure since both valves are completely closed at TDC in preparation of the ignition combustion process. Whether you're using HEI or Kettering ignition (points) now install the distributor into the engine. On both types the business end of your rotor should be pointing near to the #1 plug wire terminal. *Since the motor is on a stand you can also use a flywheel ratchet to turn the motor. Hope this brief bit helps you.
