Take a step back and think!
Running engine.
You removed distributor, hacked up a spare distributor to spin oil pump...primed engine with oil.
Replaced original distributor, engine not running...
If this information is true, the problem is simple to correct.
First, placing the crank timing mark at “0” only indicates cylinder #1 is at TDC.
This is not enough. You need to make sure that cylinder #1 is at TDC on the compression stroke.
It is easy to accomplish this with the valve cover removed. Both valves must be closed...in the “up” position with crank timing mark at “0”
When engine is at TDC with #1 cylinder on compression stroke, you can reinstall distributor with rotor pointing toward the #1 cylinder. This will give you basic timing.
I am thinking you have the distributor 180 out based on previously running condition.
if that does not fix the no start condition, you have damaged something else during the removal and reinstallation of the distributor.
Check the electrical connections and also the firing order in which you reinstalled the spark plug wires.
