I am reading that you have a camshaft and crank that are NOT in time with each other. The timing chain is not connecting the two of them. Am I correct? If that is the case then you will have to align the timing of the gears on the camshaft and the crank. If you have the timing chain cover off, then you will see a dot or "dimple" on the crank timing chain gear and the same on the camshaft gear. Those marks NEED to be aligned with each other (crank at 12 o clock and the cam at 6 o clock), when you put the timing chain on the gears. This is done by taking the camshaft gear off of the camshaft and hanging the chain on the gear and then putting it around the crankshaft as you put it back onto the camshaft and tighten the bolts.

NOW, that you have the cam and the crank in "Time" with each other you can turn the crank to get the #1 cylinder up to the top of the stroke and both of the valves are closed (the rocker arms will be slightly loose). (Pulling all of the plugs out will make this effort easier) (Make sure the harmonic dampener is sitting at the TDC mark on the timing tab) Put everything back together and drop the distributor in with the #1 cylinder at the top and the distributor rotor should set pointing at the position the #1 cylinder wire will attach.
