Grab the distributor rotor and try to turn it. It's possible (but unlikely) that the drive pin on the distributor gear could have sheared off. A better way to check on the cam timing is to pull the valve cover and look at the valve action. Get either the #1 or #6 valves "rocking"( exhaust closing and intake beginning to open) and check for piston position. If the piston is not at or very near the top, the timing gear is most likely the culprit.
