Rebuilt 318 install problem

Hang on, the wire that goes to #1 cylinder only goes into the tower marked #1, if the rotor tip is under it at #1 TDC, compression. If the rotor tip is under some other tower, then you have to make that one your #1 , And stick the rest of the wires in, following the firing order.
After a rebuild, The distributor Drive is supposed to be installed in a specific orientation, which works with an original Mopar Distributor. But your aftermarket D may not orient the rotor into the correct tower.
So start over with the #1 piston at TDC compression, then backed up to 10* advance. Next Drop the D in so the Vcan is up near the firewall,and the drive slot engaged; with the rotor pointing to the front intake bolt on the drivers side. Then pop the cap and advance the D to align the nearest reluctor vane to the pole piece, and snug it down. Then mark the outside perimeter to index where the rotor is, in such a way that you can see the mark with the cap on. Then install the cap and verify that the mark you just made is actually under a tower. If it is, then make whatever tower that happens to be, your new #1.
If the mark is not within a few degrees of the center of the tower, then the reluctor will have to be synchronized differently until it is.

Some of this/most of this, has been mentioned by others, and it may be that you have done this, and if so, I apologize for the redundancy. I just caught the remark in post #95 about plugging into #1.
