Okay, I see you actually did replace the plug wires.
That still leaves the low voltage wires for the coil and distributor.
Do the spark plugs produce spark?
Check the points for continuity when they are closed; if the tiniest little speck of crud is sticking to the point surface and keeping them from closing all the way, the car won't start.
Is the insulating washer, around the stud that the low voltage wire from the coil connects to, insulating like it should? If that stud is touching the metal of the distributor body your ignition system will be disabled.

Is your non factory coil connected to the fuseblock, and if so, is the relevant fuse intact and in good electrical condition, as well as the fuse block terminal and the wire going to the coil?


If your worried about fuel system you can start by seeing if there is fuel in your float bowls. Does the car make even a feeble attempt to fire up when you crank it over? If you have SU's, make sure that the choke cables are not slipping, and are actually opening the chokes.
