The compression seems low, but the cylinders might be washed with fuel. The compression should be higher than 130, more like 175 so it might be a tooth off.
If I remember the distributor is driven from the rear of the cam. If the cam is in time with the crank, then the distributor should be also.
Take out #1 spark plug and use a wooden dowel about 16" long into the spark plug hole. Rotate the engine slowly, watch the dowel. When it reaches the top of its travel, that is TDC. You should rotate the engine clockwise and counterclockwise when you think the rod is at TDC. You will notice there is an over center feel to the crank when it is at TDC.
Now that you have found true TDC, make sure the crank mark lines up. If in doubt, reinstall the lower cover that has the timing mark, and then put the balancer on. The timing mark on the balancer should be lined up with the 0 or TDC mark on the timing cover.
Now that true TDC has been verified, recheck the cam mark. I would pull the distributor cap and make sure the rotor is pointing directly at #1 spark plug wire.
If all this doesn't get it running, then there is an underlying problem. The spark plugs could be fouled due to the fuel injectors opening but nothing to get the engine running, so the plugs get wet.
I am only speculating and drawing on my 35+ years in the bay as a diagnostic tech.
